Hello and Welcome to Neurotalk - you will meet many great and supportive people here!!
I'm so sorry to hear about everything that you and your daughter are currently going through
I don't suffer from Occipital Neuralgia, however I do suffer from RSD (Reflex Sympathetic Dystrophy) which is also very painful, I have had it since I was 12 years old (i'm now 13). The medications that I have been on so far are Lyrica, Gabapentin, Tramadol, Paracetamol, Ibuprofen, Morphine and many others.
I hope your daughters pain reduces soon - please send her my love and best wishes.
Alison
