It doesn't sound good, that is for sure. If I was closer by I could give a good day's labour. I got my gardens turned and disced yesterday. Heading out now to cut down a tree.
Man, sounds like worst case scenario with that total tear. I've been dealing with rotator cuff tears in both shoulders for over 15 years now, so I feel your pain! With my job, I could never afford to take the downtime to allow them to heal so I have just dealt with it, but I dont think that I would be able to in your situation. It sounds like my worst days are your every day right now. Hopefully you will heal quickly, good luck!
