Good afternoon, My 62 y/o husband who is ,5 11, 178 lbs, allergic to PCN , takes no RX meds and who I consider is very good health has been experiencing calf and foot cramps that come and go when he is lays down more often than not. This has been going on for 6mths now. Relief is primarily gained if he gets up and walks around a bit. No other symptoms noted like fatigue, SOB, swelling in his lower legs, inability to walk after cramps, dislocation of the skin or loss of sensation...
