neuralgia
"I am 52 years old and have suffered from neuralgia mostly in my feet and legs.  It got so bad I could not fall asleep at night.  I take 50mg morning and night.  I read all the comments and reviews on this and other sites. They made it sound like a miracle drug and I agree. Finally I had some relief. I am having trouble with swelling and had some weight gain.  It has been worth it."
