Me-me!
I had the Gamma Knife done (for TN) done in--gosh, was it around 2001??
Anyway, I was pain free for almost 6 yrs and now have a little pain, easily controlled by a little Tegretol. Prior to my GK, I was on 1600mg of Tegretol a day + 64 mg of Gabitril. I had gone through Neurontin, Topamax, Prednisone, Elavil and pain pills--none of them helped. I was in constant pain (to one degree or another) and had huge, incapacitating attacks frequently. Now, I just have little shocks that come and go.
The actual procedure took 35 minutes. Of course, I was there several hrs to get the giant colander thing attached and for a MRI prior to the GK. Then they had me stay for about an hour after. I'm not sure why.Total was about 5 1/2 hrs.
The night before the GK, I could only eat food that didn't have to be chewed, because of the pain. I remember we ate at Cracker Barrel (we had to go out of town for my GK) and I had mashed potatoes, mac & cheese and cooked apples, because they didn't require a lot of chewing.
After the GK, we stopped at KFC and I ate fried chicken, with no pain.
About 3 weeks after the GK, I had one big shock and that was it for the next 5 1/2 yrs. Nothing, nada, zilch. No pain at all. Within one month, I was med free. Off of all of it.
I understand the usual time for the pain to go away is about 6 weeks.
If my pain gets to the point that the Tegretol no longer works, I'll be going back for another GK. The success rate a second GK is not high as for the first, but it's still the way I'll go.
Good luck with your decision!!!
