Aching Leg Aching Leg Cramps With Cerebral Palsy?

Aching leg cramps with cerebral palsy? - aching leg

I am 14 and have mild cerebral palsy. In the last two years I was the first wound knee pain in the legs downward. Sometimes, a leg, sometimes both. It happens more often when I'm tired and / or left. Now they are a pain in my arm. I go to the orthopedist, and soon I'm going to ask, but I wonder if anyone else with cerebral palsy have this pain and if so, how can it be treated?
