<s>[INST] 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. [/INST] Hello, Regarding your concern, I would explain that your symptoms are not typical of MI.  For this reason, I would recommend performing further tests to investigate the possible causes underlying your complaints: - a cardiac ultrasound to examine your heart- a Doppler ultrasound of the leg vessels to investigate for possible peripheral arthropathy- blood electrolytes- complete blood count for anemia-vitamin B12 and vitamin D plasma levels for a possible deficiency.  You should discuss with your doctor on the above tests.  Hope I have answered your query. Let me know if I can assist you further.  </s>
