Yes. At first I had to use a lot of it. Now I am down to one a day. I have had trigeminal neuralgia in the past (idiopathic) several years ago which went away on its own. Then I had this major dental abscess, brought on suddenly by my immunosuppressant for my arthritis (Enbrel). Went from a little dental discomfort to ER visit requiring IV steroids and antibiotics in just a day and a half. That happened in September. Then it happened again in March! Which brought the TN back full force again. Had to up the gabapentin for a while but I'm now back down to my "maintenance" level of one a day. (And I discontinued the Enbrel and am starting a different immunosuppressant which will hopefully not cause these problems.) I wasn't able to get in to see a neurologist until 5 months after the first incident, which wasn't helpful, although he did order a follow up MRI to see how things were doing. Didn't look like any permanent damage, but there was still inflammation in my face (from September and this was February!!), but again, this was one month before my next severe abscess.
