My own case isnt too mbad but i have to lotion up at least once everyday but i noticed when i play sports i dont have ne problems with overheating... the only time i did was when i was an alter server and had to kneel w/o ne thing to lean on... this is what use to make me break out in cold sweats and over heat.. so i guess wat im saying is that holding in a stationary position flexing the same muscle for a while is what can cause it
