I have had PN for years and years. It went full blown crazy in August 2018. I tried Gabapentin for my pain and it seemed ok at first. After taking it for several days, I realized I had a severe allergic reaction with swelling. I could only eat liquids, no solids for about a week. The PN pain was severe, so I was prescribed Cannabis. This has made a huge difference in my pain relief. I forgot to take it one day and wow, I can't function without it. It is expensive, but I would give up most anything before I would stop this med... it works!
