I developed hypersensitive peripheral nerves soon after cervical surgery in late 2022. First reacted to metal(basically all) with burning and cold patches, tightening of muscles. Progressed to fabrics(clothing, furniture fabrics and leather). Continue to see neurosurgeon every 6 months as c5-c6 didn’t fuse. Wants to do more surgery through back of neck placing 2 *metal* rods to hold vertebrae. Might help with hypersensitivity, might not. He hasn’t been a lot of help. I had a blood test done privately to determine what metal s I’m allergic to—none. Then metal patch test at Cleveland Clinic—negative for metals. Referred on to rheumatology and neurology(different neurologist). Many tests later dismissed from rheumatology but still seeing neurologist. On gabapentin(pain) and baclofen(muscle spasms) with Tylenol as chaser. One of the medical nurses or doctors said that surgeons are done with you after surgery and don’t want to deal with anything developing afterwards. Neurologist has said I might just have to live with the chronic nervous system hypersensitivity and learn ways to help with the pain. Hope you can find the help you need quickly but you are your best advocate so educate yourself on what’s happening with your body and push hard for treatment including testing. Good luck!
