The responce to joint injections is a mysterious adventure. The experiences of friends and myself seem to fluctuate so much, no matter which joint or practitioner. No two shots are unlike!
About 30 years ago, on top of my joint issues, I had an encounter with a violent patient.. resulting in a fractured sacrum and dislocated S.I. joint. I have had the whole spread of P.T., and shots. I'd say that the year long, daily P.T., had the most consistent benefit. My TENS unit has been a great addition.
The shots .. well, some great, others not! I have an open door policy with my specialist, when needed, and when brave, I give it 'a go'.
In the last 2 years, the best thing I have done for my 'back issues' is installing a tall bathroom toilet and vanity. It was amazing how much less my back feels sore! Changing the environment to suit your body's limitations has had great benefits!
It is a life long issue; a bit like having a tiger crouching in the bushes, ready to pounce!
All the best to all in keeping 'war wounds' at bay!
