I am having leg cramps beginning at about 3:00 AM. They feel like the ligaments are contracting and hurt so bad I could cry. I am a 73 year male and still very active in life. It seems that whatever the physical exercise is that I have done that day brings on these leg cramps. The only thing I have found to relieve the pain is Tonic Water. I take a number of Rx and wonder if one of them might be causing the cramps. The first ones that I question are:spironolactone 25 mg tabs, Torsemide 20 mg, Tizanidine 4 mg, and ATORVASTAIN 10 MG. MIGHT ANY OF THESE CONTRIBUTE TO MY LEG PAIN?
