hi there.

i dont have literature to send you but anecdotally i've found steroid injections around the nerve root to be helpful in the recent past.

its important to note that while you may have had an injection "into" a muscle or tendon. they would be injecting steroid "around" the nerve to calm the inflammation, not into it.

a colleague of mine recently had a client who had fallen from a horse onto her shoulder. Lots of pain around neck and shoulder who resolved about 60% with physio but he just couldnt get that last 40%. C5 seemed to at the root of a lot of her trouble so we had a pain specialist inject around her c5 nerve root area. she had instant relief and two months on its seems to be lasting. (my colleague also continued to mobilise the cx spine etc for a couple weeks)

we thought that maybe it was a traction type injury to the c5 root which had then become quite inflamed and sensitised the nerve leading to pain in its distribution. the steroid knocked out some of the inflammation allowing the nerve to get used to being moved again thus being desensitised?

this is just anecdotal but it does show a good outcome. talk it over with a pain specialist. if you are of good health with no pre existing kidney/liver trouble steroid injections shouldnt really lead to any problems but everyone is different.

all the best. let us know how things go.
