Pulled Shoulder advice?

i got hit by a sled ( snowmobile ) a few years back, tore my shoulder in 3 places, fucked up some nerves in my elbow to. lots and lots of rest, seriously like a month of maybe opening a jar of mayo, it will feel better, but ease into useing it again, my shoulder and elbow bother me to this day, cold weather dont help, phicyal thepery didnt help much for me
