[|Human|] I m a 46 yo female who went back to boxing after a 4 mouth leave due to travel/work. About 10 minutes into punching the hard bag, I felt my heart beat quickly and hard in my chest. It actually hurt to inhale 1/2 way. Later that night, I had pain in my left collarbone area and across my chest. I slept sitting up for 3 nights and then was only able to sleep on two pillow on my back. This happened 8 days ago. Today I feel also like me. However, I feel tired when I am doing normal activities like walking up stairs, lifting laundry, etc. Normal breathing is ok, but to take a deep breath still hurts slightly on the left side of my chest. Can you tell me what happened?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Possibility of musculoskeletal pain is more in your case. Your symptoms started only after your boxing practice (exertional). So chances of muscular pain is more. But better to get done ECG and 2d echo to rule out heart diseases because you are having left sided chest discomfort. If ECG and 2d echo are normal than no need to worry about heart diseases. Do following things for better symptomatic relief. 1. Avoid heavyweight lifting and strenuous exercise. Avoid movements causing pain. 2. Start painkiller and muscle relaxant Chat Doctor.  3. Apply warm water pad on affected areas. Don't worry, you will be alright. But better to first rule out heart diseases. Hope I have solved your query. Wish you good health. Thanks.
