I am 23 years old. I am feeling discomfort in the chest for the last 15 days. It started as mild discomfort on the left side. It continues all day. I do not feel it as I get occupied in some activity. There is no pain in the hand, neck, back etc. The pain doesnt increase or decrease with exercise. The pain isnt affected by breathing. I was taking Carbamazepine to control Migrane which have stopped since last week. I took a Combiflame (NSAID) today but couldnt find much difference in the discomfort.
