Hello @rezaborsi. I’m very sympathetic to your symptoms, as I have similar…intense itching, with stinging and slight burning. I have been diagnosed with Large Fiber Neuropathy caused by autoimmune disease and other complications. My symptoms get worse when I’m hot, when I sit against something or lay on my back for more than an hour. And, they’re at the worst at night, making it difficult to sleep.

Are you seeing a neurologist? I’ve not found any over-the-counter remedies that work effectively for longer than a couple hours. The best for me is a lidocaine ointment which I mix with a topical containing camphor, eucalyptus, peppermint oils.

I just got a prescription from my neurologist for a compound topical ointment -
Lidocaine 2%, prilocaine 2%, gabapentin 3%, meloxicam 0.1%. Apply 1/2-2 gm, 3-4 times per day to affected areas. Total 240 gm.
Eastern State Compounding Pharmacy, Littleton, NH.

Unfortunately it’s expensive and my insurance didn’t cover it, so I use it when I’m having a particularly bad occurrence.

I hope you find relief soon!
