What drugs can we use for pain caused by damaged or compressed nerves? I have tried Neurontin and Topamax. Neurontin caused weight gain so I stopped it. I just ate and ate...It did stop the pain though...Just cannot control what goes into the mouth....so cannot take it. My insurance company will not allow Lyrica...I think I am having problems with my eyes from the Topamax and am not certain it works alone, but might ask if I can combine it with the Neurontin to determine if it might curb the hunger, though I notice I get heart palpatations when I combine both drugs together at low doses...Anyone else experience this?
