That is strange. I just had that thought yesterday as well. Of course the timing of DD and menopause are the same. I have also wondered about a accident that I had last year with a horse biting me in the shoulder and crushing my joint and a dog bite in my right hand. All of these things in the same year that the DD presented. A MRI after the shoulder incident showed tendonitis, bursitis and arthritis. The MRI was two months after the injury when a complication arose and I saw a doctor. The shoulder has never healed to the point of no pain. What have you found out?
