I've had neuropathy in my feet for years, but my pain is quite well controlled on Gabapentin, but is a prescription only drug, but well worth asking your doctor about.
I hope you don't mind me saying, but from my own personal experience, I wouldn't encourage the use of tramadol - I was on it for several years for back problems, both injury related and arthritis in lumbar region, then got really bad sciatica for over 18 months - nothing helped it at all! Then a surgeon friend suggested stopping that form of pain relief and my sciatica disappeared within a fortnight! Apparently sometimes opioids can exacerbate the problem rather than help it. But if you do decide to stop tramadol, please do it with a doctor's help - you are meant to taper them off gradually, rather than just stop them.
I don't know if any of this helps you at all, but I do wish you all the best, neuropathy is hell!!
