Hope it goes well!

Are you a lefty? Is it your left arm? I had a pinched nerve in my upper neck c3/c4 and it made my left arm hurt tremendously. I found temporary relief with a home traction unit until I could get surgery that turned it off like a switch. I hope you get the same forever relief.

Yeah, I'm lefty. And I have an osteochondrosis. Medications and procedures helps me now. Yeah, it's stll hurt, but not like in first days. And I can even hold a cup in my hand and draw again(though not for long).
I would like to hope that I do not need surgery. It's always expensive and it's very hard to find a good specialist, when it's war in your country (It took me six months to find a doctor who would remove my wisdom tooth.)

Oh I was unfamiliar with osteochondrosis, that cannot help this condition but from my otherwise normal body nerve blocks worked for me but only temporarily and each injection came with risks, there was a situation here in the US where an ingredient used in one nerve block was contaminated with mold, omg. They sure learned from that but not before several people were paralyzed. I got a block during that time but mine was fine. Surgery was the one thing that fixed it permanently. Mine was disc replacement with cadaver bone which my surgeon wrote a book on but there is a new method available that preserves the shock absorbing affect the disk had and a fellow fur recently got that surgery. See his experience here. I wish you luck in your journey with it.
