I never took anything for it, neither last year suffering for months with my right, nor this past week suffering with my left. I avoid taking anything which has not been prescribed. Each time, the arm felt OK just hanging limp, at my side, the pain came if I tried to change the shoulder angle of the arm, to my body. I would find myself reaching over with the good arm, to take the weight of and reposition the bad one. I was fine carrying the weight of shopping bags, even with the bad arm.
Several physio appointments, last year, provided little help, just phone calls from the therapist and emailed links to exercises. It would be helpful to know what actually triggers the issue?
I think Mottie and myself had problems, in some way, with the rotator cuff, which is caused by some sort of tear or degradation or inflammation to one of the muscles or tendons which move the shoulder. A proper frozen shoulder, I think, is different. The tissues surrounding the shoulder become inflamed and inflexible and this stops the normal movement of shoulder. As far as I can see, they don't really seem to know why it happens, except often it occurs when the shoulder is immobilised whilst recovering from another type of shoulder injury.
