My father has been living with this since 1992. He left work at 52 (my age) on long term disability.
It started as undiagnosed shingles in his inner ear. Incredibly painful right there, as one might imagine. It left Trigeminal Neuralgia behind.
I drove him to Royal Victoria Hospital in London a month ago to see a specialist in head pain. He last went to that clinic 25 years ago. Somehow, he ended up at the headache clinic, not the head pain clinic, but they saw him anyway and sent some new medication suggestions to his family doctor, who has not been a big help. When London suggested Tylenol 3, he provided a prescription for only 10 of them, and told him to go back to London to get more. It can take a year to get an appointment.
My dad has tried all the marijuana derivatives, which is hilarious to me, but to no avail.
Back in the 90s in London, he was told that if anyone said they could operate, run. He'd likely be disabled from the attempt.
The pain got worse in the past year. He really can't do much. It's pretty rough.
I'm pretty sure he's been on Pregabalin. He's tried a lot of things. I'll ask.
