Thanks for your question on HCM.
I can understand your situation and problem.
In my opinion you are having mostly
muscular pain.
But since you had lefy sided
chest pain with left
arm pain, we should rule out cardiac cause first.
So get done ecg and 2d echo to rule out cardiac cause.
If both are normal, then no need to worry much for cardiac cause.
Your pain is mostly musculoskeletal in nature.
So avoid strenuous exercise.
Avoid heavyweight lifting.
Avoid bad postures in sleep. Avoid movements causing pain. Start painkiller and
muscle relaxant. Apply warm water pad on affected site.
Don't worry, you will be alright.
