What Causes Occasional Tingling In The Left Shoulder, Heart Burn And Fatigue?

Hi, I am a 57 year old male with a family history of Heart disease. My complete physical last October included ECG, all tests were well within acceptable limits. I run 4-5 time per week about 3 miles. I am a moderate wine drinker (1 glass every other day). I smoke cigars occasionally in the summer. I do have autoimmune/RA. I take Azathioprine 50MG, Prednosone 5MG both every other day (no symptoms). I take Lisinopril 10MG daily. I just took my blood pressure, 116/72 and pulse 51. but i have occasional tingling/soreness in left shoulder, hearburn, some afternoon fatigue. Sustained stress. What do you think
