Hello doctor, my age is 34 years (male) I have been feeling weird sensation on left side of my chest since 1 week, there is no pain. It usually comes at evening and night. I do exercise or jogging 40 min/day, sensation is not affecting, and absolutely no sensation in the morning. I did detailed blood test, everything is normal. Only problem is my HDL is low (30 mg/dl) and overall cholesterol is at 160. I'm overweight. No acidity/gastric, bowel movements are normal. Kindly advise.
