I dislocated my right shoulder in September, and physio once a fortnight for half an hour did not help the stiffness and was causing it to ache afterwards . However. a six week shoulder class at Leicester Royal Infirmary that I started in January did wonders. It was an hour of moving round ten activities with others who had shoulder problems. People were all at different stages and came and went accordingly, but everyone was very friendly and we encouraged each other.The physios were able to assess us as we went along, and we all worked hard because of being in a group. It was very helpful.As I was improving, but still unable to do everything, I had an extra two weeks, but am now signed off.It made loads of other muscles ache, but it was good therapy. There is usually pain after therapy as one goes a bit further each time. That is my experience, but if yours is constant pain you should definitely mention it to the physio.
