Hello,I am a 26 year old male, about 140 lbs and 62. I have a very hard time gaining weight, and have always been underweight. I am having a recurring pain in the left side of my chest, which is making me very nervous. I first began to feel it about 4 1/2 years ago. The best way to describe it is a balloon inflating behind where I imagine my heart to be, accompanied by discomfort, and sometimes sharp pain. I have seen many doctors about this issue, and have been through multiple EKGs, all indicating my heart is just fine. I dont doubt that, but this symptom is constant, and the location is stressing me out. It seems to be occurring more frequently, sometimes 6 times a day, for  many days in a row. What tests should my doctors be doing to find the cause?
Hi, The cause for the left sided chest pain is not always heart, among young people muscle pain and pain caused by spine problems are more frequent, and sometimes chest pain can be caused by anxiety as well. I would advise you to see a doctor to check if everything is normal with your spine. Take care
