I use a cream for nerve pain on the side of my face. In it is Gabapentin, Lidocaine and Capsaicin. It is extraordinarily effective. I do not have side effects. The only little thing is when I first started using it, I felt a little nauseous the first few days and it didn't seem to work perhaps the first week (don't fully recall). However, once it started to work, it worked very well with no side effects. I did have breakthrough pain, but that has lessened in recent times. It is amazing. I have it made at a compounding pharmacy. A carrier cream of some kind needs to be used.
