Hey my name is Katie. I was working out this afternoon about 5 hours ago. Well about three hours ago I was sitting on my couch and my left side starting have sharp pain under my left rib at the bottom. Well I took a Tylenol about an hour ago and it is not working. It is to the point I feel like crying. If I walk to long, sitting long, lean to my right, lay on my left side it hurts extremely bad.
Hello dear, thanks for your question on Chat Doctor. I can understand your situation and problem. In my opinion you are having musculoskeletal pain mostly.  But as a rule in left sided chest pain, we need to rule out cardiac cause first. So get done ECG. If ECG is normal then no need to worry much for cardiac cause. Your symptoms are suggestive of musculoskeletal pain more. So better to follow these steps for symptomatic relief. 1. Avoid heavyweight lifting. 2. Avoid strenuous exercise. 3. Avoid bad posture and movements in sleep.4. Start painkiller and muscle relaxant. 5. Apply warm water pad on affected site. Don't worry, you will be alright.
