I was put on lamictal for my mood swings related to a TBI. I was on lamictal for 3 months, when the leg muscle stiffness and knee pain started. It got so severe after 5 months, I demanded to be taken off of it. I was taking 25mg, even though my doctor didn't believe the problem was lamictal, he told me to stop taking it the next day. The withdrawal is living hell. I have been off it for 3 weeks and the stiffness and pain is better, but I feel like I have the flu and the diarrhea is bad. I would like to know how long the withdrawal will last? I believe I was misdiagnosed. I've come a long way since my accident and now I feel like I'm starting over. Thanks.
