Hello dear, thanks for your question on HCM.
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.
