Welcome to HCM
We understand your concerns
First of all you should confirm whether it is enraged nerve
or some sort of internal bruise
or muscular twist. It should be the second as the problem was caused during exercise.
For both the problems you can apply olive oil / sesame seed oil externally and massage
gently for 10 minutes and apply mild heat (dip cloth in hot water and apply gently with tolerable heat).
If not clears within three days, consult a GP
Get well soon.
