I have had muscle cramps in my legs, both calves and thighs. These occur usually when I awaken, and can be extremely painful. Also, they can occur in my diaphragm, during the day with any activity. I am diabetic, Hypertensive, and a breast cancer survivor. I am taking medication for all of these conditions. Could my medications be causing the cramps? My primary doctor is aware of the cramps. Any help you can provide, will be appreciated. Donna
