Question: My husband just turn 50, has cardiovascular disease. For years he has muscle cramps (charlie horse) spasms everywhere. He particularly has them MORE after exercising but they come all the time, at any given time now--just sitting or relaxing. His legs, fingers, under his arms, his jaw, etc. He takes a supplement of magnesium of six tabs a day. (online McBright, mag.) Weve tried everything from bananas to Super Complex B, potassium supplements,etc. He states he feels like he's becoming weaker over a period of time. No matter what we do anymore, a XXXXXXX horse is part of our everyday life. He has medicine for high blood, Lisinipril. In addition, IBS is random-so we thought maybe that was it, maybe his small intestive wasnt absorbing the magnesium or some other supplement. That didn't work either, regardless the cramps return. He works regularly, avid hunter and fisherman and in good shape with his weight. Any suggestion because every physician we ask does not have an answer nor makes suggestion. Just clueless.
