shoulder displaysia

I have had problems with my shoulers since I was a child. Now I'm in my 30's and realise my shoulders aren't normal like everyone elses. It feels like they disconnect at the joints. This happens regularly(daily). They now and then leave me in continous pain without realising why. Reaching out or up usually feels like they have disjointed. I have consulted a physiotherapist in the past but he couldnt help as he had never dealt with my problem. A friend said that I may have shoulder dysplasia. Could this be the case?

Hi,
Before we discuss your problem I would like to know some of the associated symptoms as well.
Where is your pain actually? What movements, if any, exacerbate your pain?
Does your shoulder ever give way? Did your shoulder previously have pain, but is now only stiff?
How long have you had your shoulder pain and have you tried anything to help it?
Any imaging studies which are been done. I would be interested to know.
Bye.
