I’ve had frozen shoulder a couple of times, once since I’ve had neuropathy. During Covid I picked up a giant cat I was fostering and pulled my shoulder somehow. I was in excruciating pain but it was during Covid when no one was seeing patients. When home remedies didn’t help, I eventually got to an orthopedist and had at least one cortisone shot (maybe 2 one month apart. I can’t recall). And with physical therapy it got better and I have full movement with no pain. My neuropathy acts up easily (it migrates up from my feet and affects my whole body during flare ups) but I had no reaction to the shot. Of course everyone is different. Hope you find relief from your pain.
