I am right there with you ! Hurts like Hell, I know. My left shoulder is worse than my right,but it seems like the pain radiates down my back and wraps right around the ribs and breathing is tough. Feels like a wall I can't break through. I try to deep breathe,it's difficult. Slow,deep breaths. I do use heat,or topical rubs. Hard to get the spots on your own,so I found a long handled applicator on Amazon that helps. I do use CBD. I find I need about 50 mg to get any relief,but you need to start small and find what works. Some forms get into your system quicker. I am also prescribed Tramadol,but I've been dx'd with fibro and on them since 1996,so by now,they alone don't do much. My doc is sending me for xray of the shoulder and cervical spine just to get a new look. He wants to make sure that there is not anything else going on, like arthritis,which I have in the lumbar spine. It's all like throwing stuff against the wall and seeing what sticks! Do you ever feel the need to yawn-trying to get that deep breath and damn,you just can't do it? Drives me nuts;short ride! Hang in there and hope you find something to get relief! Sometimes you need to bombard the pain with a combo of therapies. Good luck!
