Hi @Newbie3312 I had the same thing but the BS assistant told me they hadn’t touched the nerves and that it wasn’t their issue. Felt like someone had a knife in there and was twisting it. Weeks later I spoke to my BS who assured me they dug All around that area and the pain in the back of my arm would be because of that. He suggested I just keep taking pain relief until it went. I objected to this so did my own thing. I massaged it a lot especially when it hurt. Seemed to help a bit. I still get random stabs of pain there eighteen months later but I have learned to tolerate it.
