Hi Vestabula.
I have just read your post and from experience i would say you do have a frozen shoulder, both mine have been frozen in the past but i went into day surgery and both were manipulated ( yanked about) until they had full movement again, when i woke i was a little sore but now i have 100% movement in one and 95% in the other, i would strongly advise you to see to see your doctor, it gets worse very quickly until you have very little movement and extreme pain.
I hope i haven't spoken out of turn, i would hate anyone to go through what i did.
Wishing you well, Sharon xx
