I’m so sorry you are enduring so much pain. Have you seen a neurologist about your issues rather than a GP? They are more knowledgeable about neuropathy drugs and what works for each person. If not you might want to ask your doctor for a referral. I know when I first got neuropathy I was in so much pain until I was referred to a neurologist in the hospital and my pain went away with his help. I still have the numbness though and that produces a lot of issues as well but pain is not one of them. I hope this helps you. Keep the faith. It will get better with the proper help! Hugs
