Yeah, I misunderstood, sorry. I'm glad you enjoy your job.
I recently met a girl who was 16 with CP, she waked with a limp, her left hand was tight and she has speech problems, but had normal intellegence and understanding of the world. She suffered too with cronic pain, which apart from the speech was her most debilitating effect of her CP. The doctor had fitted her with a special pump, to her stomach I think, with which she was able to administer pain meds as she needed them, within a specified amount. This got the pain under control for her.
The pain experienced by people with CP (here in the UK) is treated very seriously, so my advice is to go to your primary doctor and ask for some options. Don't assume you have to live with it because you don't.
