I have had CRPS for 22 years. I had surgery for Tarsal Tunnel Neuritis on my right ankle, which in turn caused this chronic pain syndrome. It started out with a cold foot. Later it spread up to my thigh and continued up to the right side of my body all the way to my right side of my face after I fell over a table and hit my right thigh and bruised it. I was put on Cymbalta and started on Gabenpentin, which was increased to 600 mg 4 times a day. It has gotten my burning and hypersensitivity under control. I have my pain under control now and can live better. I am never out of pain, but it is bearable now. I have to have heat on my foot 24/7 now, but have learned to live with that. I have had physical therapy, injections, 2 Dorsal column stimulators inserted, different meds, therapy. You name it and I have tried it! I hope this might help someone on here. I will be happy to answer any questions.
