So they aren't actually doing steroid injections, they're doing temporary nerve blocks to suss out the troublesome nerves and then they'll just skip the whole steroid injection and go straight to burning the buggers.
Had my first last week and my second this week. The "relief" as it is only lasts a day tops. For me it was about eight hours. But what an eight hours! Simply magical. Just my hand and arm working perfectly, no pain whatsoever. Didn't have to wear a wrist brace all day for the first time in years. Not just the pain either, but the fingers feeling completely as nimble as they used to back before this problem started manifesting...well, almost six years now.
They DID bruise the shit out of my ribs hauling my unconscious post bariatric surgery skin monster ass back into a wheel chair and THAT hasn't been fun, but if the post ablation will feel like that eight hours did for months or years at a time, then that's something very much to look forward to.
