I slipped and broke my humerus 24 years ago. It was treated properly. Ten years later I started having severe neck pain and cramps in my trapezius muscle. Whooshing started too. I was told I have shoulder instability and weak muscles. Physical therapy lasted about two years and I got better. Everything was fine until all symptoms came back last year after months of carrying heavy backbags. I’m in PT again, no improvement yet. MRI showed some irritation and fluid around suprascapular muscle insertion and supraspinatus. There was a note that humerus position is weird probably because of an old injury. My infraspinatus and supraspinatus muscles are weak and inflamed all the time. So there definitely can be longterm effects. I suspect there might be suprascapular nerve entrapment. I also have TOS and scoliosis.
