Hi, I have servere pain In my left shoulder, I m 50 years and I m unaware of banging or damaging it, start 3 days ago slight ache, now it s unbearable, having strong pain meds and it s not touching it, Tramadol, Oxycondin. I can move my arm, it s just like a throb in the shoulder then goes like a spasm and this is agony. Even hurts when I breathe no pain down my arms, seams to be just coming from inside my ball and socket joint, plz any advice, it will be another night without any sleep, the pain is so bad
