Thanks for your question on HCM.
I can understand your problem and situation.
In my opinion you are having
musculoskeletal pain mostly because it is associated with movement and heavyweight lifting.
But better to rule out cardiac cause first.
So get done ECG.
If ECG is normal then no need to worry for cardiac cause.
It is musculoskeletal pain mostly.
So try to follow these steps for better symptomatic relief in musculoskeletal pain.
1. Avoid heavyweight lifting.
2. Avoid strenuous exercise.
3. Avoid bad postures in sleep.
4. Avoid movements causing pain.
5. Start pain killer and
muscle relaxant.
6. Apply warm water pad on affected site.
Don't worry much, you will be alright.
