I have peripheral neuropathy in my legs and arms from an accidental overdose of lithium ten years ago. I am no longer on lithium after that episode. My doctor put me on Lamictal in November, and stopped me at 150 mg. The past month or so my neuropathy has been getting much worse. I have read that it can be used as a treatment for neuropathy. Has anyone heard of it making it worse? I have moved out of state and do not have a doctor set up.
