calling all doctors

ok ill calling all doctors for advise.

i practice upward of 6 hours a day, that is a normal day. so my hand is tired and alittle sor before i go to bed.

i was born with cerebal palsy... im like 99.9 present "normal". part of the cerebal palsy is spastic diplegia im not sure if this is whats cuasing it...

while my hand is sor today and i will cut down on the all day playing, i wanted to ask the people who KNOW... whats better to relax MY fretting hand hot or cold.

this is the first time its been this sor

sorry for any misspelt words...
