Flare is tòradol shot, manage the escalation with Valium as muscle spams will wrap around the nerve and start big flaring. if you can use Valium as the muscle relaxant you are on top of it.

My maintenance is Endocett as need up to two a day, most days I try just Alieve, tòradol 10 mg pill once a month to get on top of the pain it is a kick butt anti inflammatory. You have to not over due it, it can cause bleeding if over used. No more than 5 days in a row. But if I'm at the second day I run to an urgent care and get the tòradol shot.

Near daily Valium keeps me in check, either a half or the whole. I can take daily but hate taking meds.
Ugh even my thyroid I occasionally miss.

If I am ER level after all else fails, shot of Valium, Tòradol and morphin. This has been very rare since I maintain with Valium and Endocett and reduced work schedule. This is often the head pain flare of cervogenic spasms. When I have tears running from the pain.
