I have been having this pain on right side of the chest. It happened once in the past I took pain killer and it went away. I went to a doc he said it's muscle spasm. Earlier the pain was coming with movement now it's there, he had given me medicine but m wondering do I need to stop going to the gym completely ? Could their be any other reason for the pain? It's not much but slight pain. Could I do like light weights at the gym ?
