Hi
@wnek - i have neuropathy in my face and neck. It has been getting more pronounced and extensive over the years. The intensity comes and goes in the short term with no apparent pattern. At its worst it is becoming debilitating.
I have come to the conclusion that when it comes to neuropathy just about everything is guess work. The tests that can be done (nerve conduction tests and MRI scans) are crude and blunt. I have had all done and nothing has been seen that could account for my neuropathy. If it were due to something big - stroke, brain tumour gross deterioration of the nervous system - then the tests are likely to have seen something. They have not, so I can take some solace from that. The neurologist, not a natural guesser, will not give a diagnosis and says that a root cause for my neuropathy might never be found.
Your GP/DN might be adamant that your neuropathy is diabetes related but you have to bear in mind that it is a guess. They may be good guessers and be right, but it is nevertheless a guess.
I have tried all the medications approved for neuropathic pain. None have had any effect on the neuropathy. The last thing the neurologist suggested was to take pregabalin and try and get to near maximum recommended doses by building up the dose up very slowly. I have just tried that getting to half max dose in 4 months but the side effects - basically addling your brain - were too much and I have come off it. My GP, who is being very helpful, has suggested some off-licence drugs and I am tying some of those in combination with low dose pregabalin. I have no real confidence that anything will work.
Sorry to be a bit downbeat on the subject but that has been my neuropathy story over the last 12 years or so. I have just learned to live with it.
