Rigor mortise is setting in

Its been over a month now since I woke up with a pinched nerve or something from sleeping and my neck, shoulder and arm are still in pain. Not as bad as the few week or two but still really unbearable. I can only be in certain positions for a few mins before the pain builds up. I can barely focus on getting my work done. I tred taking Alive pills, they didn’t do anything. Tried using a icy hot muscle cream that I had on the boat but I think it was a few years outdated. The only thing that seems to work is drinkin. Cheers!
