I have been using a high CBD strain of Cannabis flower. I also rely on a high CBD strain of oil from a vape. I am in a state that allows for medicinal use of cannabis. I have not taken any pharmaceutical for the past year for my TN. Gabapentin gave me facial edema. Hydrocodon was a drug I had used for about twenty years for back pain. I was prescribed the cannabis/CBD for the back pain but the usage also keeps my TN miraculously in remission. I don't even take a Tylenol any more!
Sometimes like now, I hate to hear myself talk about being in "remission", because I have and do experience the painful,puzzling condition of TN.
I try to be positive and sensible about having the condition and I wish you and everybody the best.
