One word for trapped nerve pain; pregabalin. It truly is miraculous, the problem is still there, but you just cant feel it any more.
I fucked up some nerve in my neck/top of my shoulder zonked out in a bad posture on benzos. I've been given a list of exercises to do, but as the pain only occurs if i lift heavy objects sideways and up over my head with my left arm, i just avoid lifting things in that way.
