It's been a year since my TN diagnosis. Since that time I have experienced some improvements.
I've found that if I take my focus off the TN, I can almost block the pain entirely at times. And when I can't block it, I try to simply think of it as a 'sensation'... 'not pain'... just a feeling that doesn't warrant any alarm from my mind or body. I have medication I can take, too, when it gets out of hand. All of these methods of dealing with my TN seems to be working for me for the most part.
In addition to the above, I have also found the majority of my triggers: holding a phone to my ear, bending over, looking too far up/down/or to the side; loud noises; wearing an eyemask at night (big no, no!); and eye strain. I now limit/avoid these activities, especially during a bad flare up.
I hope everyone else here is doing well. TN is a difficult disorder to handle. There are so few answers in terms of treatment.
