http://www.medications.com/effect/view/25180 I was treated with lamictal for bi-polar II . It did help even out my mood which swung to deep depressions and rare (unfortunately) hypomania.

I never linked the pain with the lamictal until I read the comments on this website. I hope that once I get off the lamictal, the pain will subside some. http://www.medications.com/effect/view/25180?item=3463 Sun, 20 Jan 2008 12:39:05 -0500 http://www.medications.com/effect/view/25180?item=4204 I have been on Lamictal about 1 1/2 years and have also experienced severe arm and leg weakness, especially my knees. I find it hard to even do laundry. Oh, and the memory loss is horrible. I'm only 39!! I have started weaning myself off the Lamictal. http://www.medications.com/effect/view/25180?item=4204
