I m a 56 year old man, in poor health with type II Diabetes, Hi BP. Severe depression & take about 10 or 12 different meds, I just had an attack of cramps that started in my left leg & then moved to my right, the pain intensity was like nothing I have ever experience in my life!!!!!!!!!!!!!!!! it lasted about 10 min. I took 500 mg of niacin, I chewed up a valium & swallowed another one whole, I drank about 30 oz of water with 1/2 tsp of salt I chewed up 2 325 mg timed relies aspirin & took another whole one. I kept my legs moving while standing & holding onto a counter & the pain passed about 5 more min after taking the above pills. I still have residual pain in my groin while sitting here at the computer, about 10% of what it was at it s worst. I may of been a little dehydrated. Any idea what the hell just happened to me? Gary
