Amitriptyline not working anymore

Hi, I had Trigeminal Neuralgia in the crown and left side down of my head and know how much it hurts. I was denied sleep and my scalp became swollen from the terrible pain. I was put on Gabapenten and within 3 months the pain had all but disappeared. I stayed on it for another month until I was pain free and slowly came off the meds. You are on a high dose, higher than I was, and I feel for you that the pain is breaking through. However, I'm not overly sure that upping the Amitriptyline would help much and this would be best discussed with your GP. Where on the head/face do you suffer the pain? Gabapenten is known to be the most helpful drug for this painful condition and if it is breaking through the dose you are on the only other alternative I know of is Pregabalin (very similar to Gabapenten and used for neuropathic pain as well). I am on Pregabalin for a different pain now and it works well for me. The side effects can be daunting but some patients need to take it just to get a pain-free life. Talk to your GP about this - I know of some people who have to swap between the two as one will cease to work and then swap to the other and then back again as necessary. Sorry I can't be  of more help but hope you get something sorted soon.

Isn't it strange how side effects differ between patients to such a degree?! I imagine that the trigeminal neuralgia in the face is even more distressing than the back of the head. Gabapenten worked for this but when I suffered severely trapped sciatic nerves because my lower 3 vertabra had crumbled (severe Osteoporosis) Gabapenten did not touch the pain and made me dizzy along with horrendous vivid nightmares...that's why GP put me on Lyrica. I started on Amitrip but that triggered a rare form of sudden onset Glaucoma and I nearly went blind on it so can never ever take it again. As I said, it is strange how these drugs individually cause different side effects in patients! Let me know how you get on upping to 20mg.
