Thanks for your question on HCM.
In my opinion it is neuritic pain only.
But as a rule, any left sided
chest pain must be rule out for cardiac cause.
So get done ECG and 2D Echo to rule out cardiac cause.
If both are normal than no need to worry much.
It is mostly neuritic pain.
This can be due to
1.
Nerve entrapment
2. Vitamin B 12 deficiency.
So get done B 12 level. If low than start supplements.
Also follow these steps.
1. Avoid heavy weight lifting and strenuous exercise.
2. Avoid bad postures in sleep.
3. Take good painkiller and
muscle relaxant.
4. Apply warm water pad on affected site.
