Hi - I just vomited a small amount of food I finished eating. When I threw up, besides the chest strain one normally feels when vomiting, I also felt what I would describe as a muscle pain in my left arm bicep. Similarly to if I had done too much weight lift for this muscle. It lasted about about 30 seconds, then it left. Lately, I have gained a lot of weight due to excessive and unhealthy eating. The pain only last some seconds after I vomited, but it was the first time I ve ever felt that slight pain in my left arm muscle. Could this have been some type of heart attack? I do NOT feel any pain anywhere (i.e. chest, arm, etc.). Should I seek immediate attention?
