Peripheral Neuropathy - If gabapentin or pregabalin don't work, what can I do?

This excerpt from Harvard Medical School/Harvard Health Publishing may give you something to discuss with your doctor:
"Did you know that antidepressant medications are often prescribed for people without depression?

It’s true. Antidepressants are frequently prescribed for chronic pain, especially pain related to nerve disease (called neuropathic pain), chronic low back or neck pain, and certain types of arthritis."

In fact, some guidelines for the treatment of chronic low back pain and osteoarthritis (the most common type of arthritis) include antidepressants. One antidepressant in particular, duloxetine (Cymbalta), is FDA-approved for these conditions.

I find that keeping my feet still - rather than tapping them - helps a lot with the pins and needles, pain problem,.

My pain management doctor put me on Cymbalta (now generic) more than 20 years ago. That is the best thing I've found so far for my horrible neuropathy in my feet from chemo. She has since added Lyrica and Amitriptyline at night for sleep. Couldn't survive without these. Before Cymbalta, I'd either drink at night for relief (didn't work but at least I didn't care!) or else I'd sit and cry. My feet still feel like bee stings at times, but Cymbalta really works for me. I ran out once and the pain was back within 2 days. Good luck finding something that helps.

The only thing that helps me is Osteopathic treatment. I tried a lot of things prior to that but nothing helped. I go every other week and it definitely helps temporarily relieve all my pain. The problem is finding a doctor who does it and takes insurance. I got lucky and found an amazing doctor.

I have peripheral neuropathy as well. Try CET, EBN5 or Metanix, mesenchymal stem cells , and spinal cord stimulator. I did the first 3 and am going to do the SCS. And for instant pain relief, opioids are the only thing to help me.
