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 better to rule out cardiac cause first as your
chest pain is on left side.
So get done ecg.
If ecg is normal then no need to worry much for cardiac cause.
Pleurisy ( inflammation of
pleura ) can cause chest pain on breathing.
So get done chest x ray to rule out pleurisy.
If both are normal then no need to worry much.
You are having tenderness (pain on touch) with worsening pain on movement s, these suggest musculoskeletal pain more.
So better to follow these steps for better symptomatic relief.
1. Avoid heavyweight lifting and strenuous exercise.
2. Avoid bad posture and movements in sleep.
3. Start painkiller and
muscle relaxant.
4. Apply warm water pad on affected site.
Don't worry, you will be alright.
