Hi, i m a 53 yrs old male - i had a n MI 14 years ago & have been on heart meds since then. I had angioplasty at the time - no recurrance since. I feel tired & feverish in the evenings, i sometimes get night sweats as well. I am also starting t get involuntary muscle spasms / cramps in my legs after a days work on the beat as a policeman. There are times when i also feel very tired & drained after work that i dont feel i doing anything else. Is there something wrong with me . . .? or is this normal for someone my age & history of MI.
