I have just come home from a week in hospital and a barrage of tests, I have been diagnosed with Small Fibre Peripheral Neuropathy, I also have crohns disease. The Neurologist is researching if it is linked to the Humira but he seems to think not.... There is a link between crohns and peripheral neuropathies, I had actually discovered this when researching and trying to find out what the heck was wrong. Personally, I think there is a link between the Humira and the neuropathy, everything else that it could possibly link it is ruled out, ie diabetes and b12 and I have had every test known. If it is possible to hit rock bottom .. then i am there. I have been given lyrica for the pain, i can take as much as i want... omg, it is doing my head in.
