I am experiencing at night severe leg cramps in both legs. I take blood pressure medicine and cholesteral prescription drugs. Could they cause this? My doctor is out of town for a week and I wondered if an over the counter leg cramp medicine would help. The medicines I take are losarian and simvastatin. This seems to happen when I take these two. I left both off and went out of town for 2 days and did not experience leg cramps. I have a pace maker and stents in my upper legs and heart. When I talked this over with my primary she suggested I take tonic water with quinne. These cramps last about 5 to 10 minutes and when and if I can get off the bed and walk it seems to ease slowlyl. Thank you
