Hi Lisa, and welcome to the ANA forums. So glad you have found us--you'll find a wealth of info and support here.
I'm in Massachusetts, too, and had a 1.8 cm AN (a regrowth of a much larger tumor removed 20 years ago) removed on June 24; the symptoms that led me to a the diagnostic MRI that uncovered the recurrence were similar to yours: Trigeminal neuralgia-like pain, intermittent and very mild, though, and (here's the kicker) on the non-AN side.
I'm now 2 weeks post-op after a quick, very successful surgery (total removal, no complications), and am doing very well (my hearing and balance were sacrificed in my first surgery, so I've made all my amends and there were no new surprises this time around). Other than major league fatigue, my big issue has been--you guessed it--TGM-like pain, this time on the right (AN) side, and much more intense than before. (My main trigger right now is trying to do too much orally at the same time--ie if I try to hold a conversation during a meal, YOWCH!)
According to my truly wonderful neurosurgeon (Dr Robert Martuza at MGH), this symptom is a temporary one, due to the trigeminal nerve "waking up" now that the AN that was compressing it is gone. The analogy he provided was to think of how after your leg falls asleep, you experience pain as you stand up and try to get it to "wake up" again. Anyway, it should resolve as part of my healing process; though Dr Martuza prescribed a medication ("Neurontin") that's used to treat nerve pain, I think I will probably just be patient (and try to refrain from talking while I eat
)
The other piece of info I can share with you is that Dr Michael McKenna (of Mass Eye and Ear) was to have been part of my surgical team, but as it turned out the procedure he was going to do had already been done in my '89 neurosurgery (Dr Martuza didn't learn this till they opened me up, because my '89 medical records had been destroyed by the FL hospital--oy vey!)
Dr McKenna still made it a point to visit me while I was hospitalized--I can't say enough good things about him (and like Dr Martuza's, his rep is stellar).
Hope some of this info is useful to you, and feel free to PM me with any questions that may come up. Since your AN is small, you have many options and plenty of time to research them. Good luck to you on your AN journey!
