I origionally jacked my shoulder swimming for like 14 years... and then in the last year I've been in two car accidents and that made it worse.... and the last accident I Was in totally jacked it up.. So like.. if I lift heavy stuff or if I use it too much or even sleeping on it wrong makes it hurt... and the pain spreads to my chest so if I move it just right I get shoulder and chest pain :) woo :) I actually have some epsom salt.. I used an ice pack earlier... that seemed to have helped a little bit but we'll see... :) so mysterious person... who might you be?
