I have pn but also what they feel may be rsd and possible fibro auto immune issues. I used to be on Cymbalta. Anyhow I am clueless about supp but have been to many docs and just saw a holistic one who had started me on some. I will share magnesium glycinate,calcium with d I have osteo,glucosamine msn,kaprex,I am suppose to take dha:epa and gla forte but right now flax seed oil pills because of my eye issue and I need to stick with one oil he said.I take vitamin c,women multi. Many here take b12 which I don't and b complex. I used to take both though but stopped just cause my levels are high though usually not a concern with b vitamins. Have you had blood work lately? That may help you establish more on supp.
