My doctor added Wellbutrin to my medications because I was having problems with depression. Within a couple of days a very persistent (years long) and very severe nerve pain down the outside of my right leg just disappeared! I was on fentanyl, methadone, Gabapentin, and oxycodone and still the pain was so severe it was hard to use that leg normally. It's been two months now on the Wellbutrin and the pain has not returned. I've quit methadone and am in the process of tapering off the fentanyl. It's been many years since I had anything positive to say so I wanted to share
