Arm Slings only made for Fats Week 3 recovering from rotator cuff surgery, dom hand, excuse typing.  My neck & back are killing me because this arm sling is big enough for my THIGH.  Line it with pillowcase the nurse said, great you know the pillow fits too!  I told her it is too big for my shitlord 30" waist Dad.  When I go in for an adjustment the nurse admits they have ONE SIZE ONLY and I don't have a stomach to rest the arm on.  WTF   She said I am lucky bc these are usually so small peoples hands hang out the top side.  I don't know how the fuck that's possible.  My sling would fit a marine.
