Welcome to the NeuroTalk Support Groups.
I just wanted to suggest you try the Search feature. I just did and found many past threads/posts by using the keyword "acupuncture".
p.s. just ran a search on TN forum here for Gamma Knife and there are a few other posts for that as well.

I don't have TN but I have had Gamma Knife stereotactic surgery for brain mets melanoma.
I'm sorry you're in so much pain. I am wishing you all the best for your procedure.
take care.
