I had a displaced Rotary Cuff joint quite a few years ago which was so painful, to make matters worse I then fell on that shoulder and shattered the shoulder joint completely the surgeon I saw said it was not in my best interests to have a replacement shoulder joint as it was so badly damaged and surgery would not make any difference.
I have lived with the discomfort ever since it has weakened my right arm and now I cannot use it to its full potential,I can still feel the bits of bone in my upper arm & shoulder area but have learnt to live with the discomfort.
