June 13, 2012 - There's new hope for cancer patients who suffer from the painful, tingling feelings caused by chemotherapy. Researchers followed 231 patients in a clinical trial and say 59 percent of those who took the antidepressant drug Cymbalta experienced pain relief. That pain is usually felt in the toes, feet, fingers and hand and doctors say it can become so severe, they have to cut back on chemotherapy doses.Researchers believe Cymbalta works because it increases neurotransmitters that interrupt pain signals to the brain.
Also, too much exercise may be too much of a good thing. Recent research suggests chronic training for and competing in marathons, iron man triathlons and long distance bicycle races may cause structural changes to the heart and large arteries that can lead to myocardial injury and heart rhythm abnormalities. Last March, legendary ultra marathoner, Micah True, died suddenly while on a routine 12-mile training run. An autopsy found his heart was enlarged and scarred.
