What type of pain are you having (burning, aching, etc.)

I've found Tegretol to be helpful for the aching type pain. I'm on a low dose 100mg twice a day. I got used to the dose pretty quickly and it doesn't make me too tired. I tried increasing the dose a while ago and it was too much.

It could also be that your activity level is causing more pain. I know if I do too much my pain level sky rockets.
