I found a low dose of amitriptyline worked well for my neuropathic issues, but the chemical hangover was so intolerable the next day I couldn't carry on taking it. Not everyone gets that, so it's worth a try. I might even give it another go, if I can find some reassurance online that it goes away after a while.
I take codeine and paracetamol on as-needed basis for gut pain, but it doesn't touch the neuropathic stuff. In fact I think it was oxycodone which triggered it in the first place, but that's another story.
Dx Crohn's in summer of 2000. (Yay )
Tried and failed: 5-ASAs, azathioprine, 6MP, Remicade, methotrexate, Humira, various diets.
Had surgery Feb '13 - subtotal colectomy with end ileostomy. First thing to put me into remission in 13 years.
Had second surgery 10th July '15 to reverse the stoma and connect the ileum to the rectum. Officially flaring again. The fun never begins.
