Thanks for your question on HCM.
I can understand your situation and problem.
It seems
musculoskeletal pain mostly.
But, since it is left sided
chest pain, we need to rule out cardiac cause first.
So get done ECG to rule out cardiac cause.
If ECG is normal then no need to worry for cardiac cause.
It is musculoskeletal pain mostly.
Try to follow these steps for better symptomatic relief.
1. Avoid heavyweight lifting, push ups and other gym exercise for atleast 1 month.
2. Avoid movements causing pain.
3. Avoid bad postures in sleep.
4. Start painkiller and
muscle relaxant.
5. Apply warm water pad in affected site.
Don't worry, you will be alright and will able to start your exercise soon.
