| | Re: Cortisone Injections
I haven't had cortisone injections into the TMJ itself, although I have had my shoulder and back injected. I've usually found that it can take up to 3 days to get some relief. If you don't get relief from your migraines, you may visit a pain management specialist and see if you have any muscular trigger points - those can be injected too and can work wonders!
Hope this helps!
