Welcome to HCM
We understand your concerns
I think there might be no reason to worry. Cramps and pain often go together and we feel very much affected because we will not be able to move our affected portion. After much exertion, when we move the part, it pains, or it leaves a awkward feelings which our brain translates as something wrong and takes preventive measure like dizziness
. It is mechnism by the brain to avoid over strain, the blackout
. Don't worry. Consult a physician if need be. Good luck.
