What's Really Causing Your Foot Pain?


Your feet bear the weight of your entire body and when they're not properly supported or they're expected to bear more than they're designed to carry, they react with pain. The delicate network of bones that make up the feet and allow us to walk and balance can get pushed out of alignment, which can irritate the joints, skin, nerves and connective tissue. 
Weight loss, proper hygiene, and the right shoes are among of the most common recommendations doctors make when their patients come in with painful feet and ankles. They might also look for medical conditions associated with foot pain like diabetes and heart disease, (which can cause nerve damage and circulatory problems in the lower extremities) or broken bones. But while those conditions do cause feet to become painful, the most common causes of foot pain are:
  • Fallen arches, flat feet, or high arches that don't get enough arch support in a shoe
  • Bunions, calluses and corns, often caused by poorly fitting shoes
  • Hammer toes that curl down into a claw-like shape
  • Arthritis, inflammation of the joints in the foot
  • Plantar warts, which form on the sole of the foot and become painful when stepped on
  • Bursitis or tendonitis of the ligaments, tendons and surrounding areas
  • Morton's Neuroma, a bundle of thick nerve tissue between the toes
  • Gout, a disease process caused by buildup of uric acid in the toe
  • Sprains, especially in the ankle
  • Plantar fasciitis, inflammation of the connective tissue in the bottom of the foot
  • Stress fractures, caused by pressure, impact, or trauma
  • Fungal infections like athletes foot

Foot Pain Prevention

How do you avoid becoming a foot-pain victim? Try these methods:
1. Wear good shoes with low to medium heels and good arch support. Make sure they're appropriate for the activities you engage in. Don't substitute tennis shoes for running shoes or wear your old Keds to play basketball. Instead, consult a sport shoe expert and invest in the right shoe for your sport. Wear high heel shoes and flip-flops as rarely as possible. 
2. Practice good foot hygiene. Wash and dry your feet thoroughly every day, wear clean socks, and contact your doctor if you see any rashes, cuts, sores, or abrasions. Always wear non-skid shoes on wet, slippery surfaces and locker room floors. 
3. Exercise regularly and cross train to keep all the muscles in your ankles, legs, and back strong and to prevent overuse injuries in your ankles and feet.
Have your feet checked as part of your regular physical examinations. If you have diabetes or heart disease, have your doctor examine your feet every time you see him/her and as soon as you notice any alterations.

How to Get an Accurate Blood Pressure Reading


Blood pressure measures the force of blood against the walls of your arteries as your heart pumps. The top number (systolic) indicates the maximum pressure the heart exerts while beating. The bottom number (diastolic) is the pressure in the arteries between beats. Physicians consider a difference of more than 40 mm Hg between the two abnormal (this is called pulse pressure).
Factors That Affect Blood Pressure Readings
Stress and anxiety. A stressful situation can cause a dramatic, temporary spike in your blood pressure. A single incident is not cause for alarm; however, if this happens frequently, it can damage your blood vessels, heart, and kidneys. Stress can also cause you to engage in behavior that may further damage your heart, such as smoking or drinking.
The season. Blood pressure tends to be higher in the winter because low temperatures cause your blood vessels to narrow so you need more force to push the blood through your body.  
Alcohol. Drinking three or more drinks at once may cause a temporary uptick in blood pressure. Over time, excessive drinking may cause a long-term increase.
Daily patterns. Your blood pressure is usually lower while you sleep and shortly after waking, then rises throughout the day, peaking in mid-afternoon.
Caffeine. Coffee and other caffeinated beverages can also cause a short but dramatic increase in your blood pressure.
Measurement errors. Your blood pressure measuring device may not be working properly, or you (or your healthcare provider) may not take your blood pressure correctly, which can cause a false high reading. Even something as innocuous as a tight belt can affect your reading.
If you experience a high blood pressure reading, try again later. Take a walk or practice slow, deep breathing so you're calm before you try again. Drinking water and avoiding certain foods, such as dark chocolate, garlic, and bananas beforehand may help ensure an accurate reading. If you continue to get high readings and you've ruled out outside factors as possible culprits, then see your physician. You can make simple lifestyle changes to lower your blood pressure, or if appropriate, seek medical care.

10 Ways to Eat Well When Life Is Stressful


If you eat in response to stress, you are not responding to real hunger but instead to a coping mechanism—comfort food.
A study reported in Physiology Behavior found that 73 percent of participants reported eating more sweets and fewer meal-type foods, such as meat, seafood, fruits, and vegetables, during periods of stress.
Whether you overeat or eat poorly during times of stress, it helps to do a little "self-monitoring," and pay attention to your eating habits and the types of foods you eat.
Stress management tactics such as exercise or meditation usually require a long-term plan. But you can start with these tips to help you take control of emotional eating:
  • Maintain a normal eating schedule. Start with a healthy breakfast and eat a meal or a healthy snack every three to four hours. Eat enough to feel satisfied but not stuffed.
  • Don't skip meals. When you skip or delay meals, you become overly hungry and are more likely to overeat and less likely to make healthy food choices.
  • Keep healthy snacks on hand and ready to eat. If you start to randomly eat during stressful times, stock up on nutritious snacks such as cut-up raw vegetables, vegetable juice, fresh and dried fruit, whole-grain cereals, reduced-fat cheese sticks, and yogurt.
  • Plan your snacks. Schedule "mini meals" once or twice during the day so that you won't get too hungry. Rather than grabbing a handful of chips or cookies from the store, sit down to a healthier combination of foods such as a dozen grapes and a small container of yogurt sprinkled with cereal.
  • Pay attention to hunger. If it's not your normal meal or snack time but you are reaching for food, ask yourself if it's real hunger or emotional hunger. There are ways to tell: Real hunger comes on gradually, while emotional hunger is usually sudden and intense. Emotional eating involves cravings for specific types of foods as opposed to the combination of foods normally eaten at a meal.
  • Eat slowly and mindfully. Use mealtimes and snack times as rest periods. That way, you'll slow down and focus on your food rather than on the events that are causing you stress.
  • Pay attention to feelings of fullness. If you're eating while stressed, you are more likely to eat when you're not really hungry, and to keep eating even when you're full.
  • Enjoy your favorite foods in moderation. There's no point in denying yourself simple pleasures when you're under stress. Enjoy your favorite comfort foods in reasonable portions and in the context of an otherwise healthy diet.
  • Drink plenty of water. When you go to grab food, grab a cup or bottle of water instead. Use the time while you're drinking water to figure out if you're really hungry or just desire food for comfort.
  • Avoid consuming excess caffeine or energy drinks when you are already feeling over-stimulated.

Apple Cider Vinegar: Is It a Super Tonic?


Used as a salad dressing, apple cider vinegar could also be used as a natural remedy to help ease a sore throat, relieve sinus congestion, calm intestinal troubles, and rid your scalp of dandruff. Also, if you have diabetes, apple cider vinegar could even help keep your blood sugar balanced.
Although cider vinegar has not been subjected to a great deal of scientific investigation, many documented personal anecdotes and clinical reports seem to confirm what advocates of natural folk medicine have been saying for centuries about its curative powers.
If you want to test the effectiveness of apple cider vinegar for any of the following conditions, use these formulas as guides:
  • Sore throat. Gargle with a small amount of slightly diluted apple cider vinegar sprinkled with a pinch of hot (cayenne) pepper.
  • Cold and cough. According to Penny C. Royal, author of Herbally Yours, homemade cough syrup made with apple cider vinegar, honey, and spices can help soothe a persistent cough. Combine 1/4 teaspoon of ground ginger and cayenne pepper, two tablespoons of water, one tablespoon of honey, and one tablespoon of apple cider vinegar. Cover and refrigerate the mixture until ready to use, then take one teaspoon at a time.
  • Dandruff. After shampooing, rinse your hair with a combination of one part cider vinegar to three parts water, or two tablespoons of vinegar diluted in six tablespoons (or 1/3 cup plus one teaspoon) of water.
  • Diarrhea. Dilute apple cider vinegar with water and stir in a tablespoon of honey.
  • Food Poisoning. Apple cider vinegar's antimicrobial properties may help offset gastrointestinal symptoms associated with food poisoning, according to the University of Maryland Medical Center. They recommend adding two teaspoons of apple cider vinegar to one cup of water, and drinking this combination several times a day.

Other Uses for Apple Cider Vinegar

Besides treating minor medical disorders, diluted apple cider vinegar will clean hard surfaces around your house such as kitchen counters and appliances.
Try dabbing a little under your arms for natural odor protection. Vinegar alters the pH of your skin, which discourages the growth of odor-causing bacteria.
As a home remedy, apple cider vinegar may help soothe the symptoms of many common ailments, but it is never a substitute for professional medical care. If your symptoms persist, or if you have a fever or a serious medical condition, speak to your doctor.
Also, too much apple cider vinegar over time can lower your blood potassium levels and increase your risk of developing osteoporosis. If you regularly swallow straight cider vinegar for any reason, Harvard University's Dr. Richard Lee recommends that you rinse your mouth with plain water to preserve the enamel on your teeth.

Considering a Cardiac Implant? What You Should Know


For some patients with serious heart conditions, a defibrillator (a device that helps the heart do its job) can be lifesaving. As with all medical interventions, however, there are benefits and risks. You may have heard about recent studies that report increased rates of infections in patients who've had one of these devices surgically implanted.
There are two main types of implanted defibrillators:  ICDs (implantable cardioverter-defibrillator) and CRT-Ds (cardiac resynchronization Therapy Defibrillator). A defibrillator monitors the electrical activity of the heart. If it detects a potentially dangerous change in the heart's rhythm, it will send small pulses of electricity to shock the heart back into its normal rhythm. Defibrillators are nicknamed "emergency rooms in the chest" because they can intervene when a patient's heart fails, potentially saving the patient's life.
The use of defibrillators doubled between 1993 and 2008. During the same time, the number of implanted device-related infections tripled. While most surgical wounds are likely to become contaminated from bacteria on the skin or in organs, some may progress and become clinical infections. Cardiologists estimate the risk of surgical site infections at five to 20 percent. Infections can prolong patients' hospital stays and may even lead to death. Patients who undergo surgery are also at risk for respiratory, urinary tract, and other bacterial infections.
Defibrillators can fail, especially CRT-Ds. In one study of 3,253 patients who received a CRT-D, 416 had a device-related event by 18 months, and of those, 390 needed surgical intervention. By four years, 50 percent needed surgery to replace the batteries. During the same time, only 10 percent of patients with an ICD needed an intervention (13 percent for dual-chambered ICDs). Furthermore, the rate of infection in patients with a CRT-D was higher. The researchers emphasized, however, that these events were not associated with worse clinical outcomes and did not change the risk of death.
Some heart specialists are also concerned that many patients who receive defibrillators don't actually need them. In one study, researchers found that nine out of 10 patients received no medical benefits from the device.
The FDA collects information about defibrillators, but it's not easy to analyze the data and not all device problems are reported. Furthermore, it's hard to calculate the costs and benefits of cardiac implants and to determine who is actually going to benefit most. If your cardiologist recommends an implanted cardiac device, have a frank discussion with him about all the potential benefits and risks.
