Hi folks:
I never felt right when taking anticonvulsants and it never really helped. A friend uses oxcarbazepine, which reduces risk of some blood disorders (vs. carbamazapine) and she gets relief, but is gradually cranking up the does.
I posted a while ago that I was using the PainShield low-energy ultrasound device with success. After about 2 months of use, I have been able to stop regular use altogether. If I start getting electrical zapping, I use it again for a day or two and get durable relief. I still have muscle pain in my jaw muscle if I talk or chew tough food. I think that 10+ years of TN pain has damaged the muscles through spasming (they feel "wiry" on the affected side).
Some of you reacted skeptically to my report and others had concern about the ultrasound messing with your brain. I was more concerned about the blood pressure spikes I would get during the pain (BP going from 110/70 to 180/130...). Also, God only knows what the ACs do, so there are no "free lunches" in TN. In 10 years I have never been as free of pain for as long as I am now.
There are a few tricks to using the PainShield properly that I discovered on my own. One is that the transducers need to be VERY SNUG against your face to work. Air dissipates the waves. I tried wrapping my head with this elastic thing that PainShield recommended, but it was uncomfortable to sleep and too easy to dislodge the transducer while sleeping. I discovered "KT TAPE Original Cotton Elastic Kinesiology Regular Therapeutic Tape" on Amazon, which is precut into 10 inch strips which can be further easily used to make four 1" x 5" strips. It is slightly stretchy, and I tape the transducer to my face with an "X" formed by the two of the pieces of tape. Very snug, but easy to peel off in the morning.
The other trick is WHERE you put the transducer. You want it on BONE, not flab, but close to a trigger point. Even then I had to experiment to discover which trigger point was crucial. For me, it was high up, where my cheek bone meets my jaw joint. BTW, I have ZERO financial interest in the PainShield (except the $600 bucks for the device and another $200 for spare facial transducers)!!! It was an expensive experiment, but there is a 30-day money back deal, and now you would have to pry the device out of my cold dead hands...
It is a bit tricky to use (operates 6 hours per night, has to be recharged every day, taped on your face every night, etc.), but for me that was better than wolfing down hundreds of grams of meds. My heart goes out to all of you. Hope others have the opportunity to try it. SwedeP
