Maybe you just need a break?
Do you work out? I´ve had a lot of shoulder problems in the past, maybe not as bad as you, but still. My physio didn´t help either.
But most of it went away when I got a TRX (google it) and started working out with that and since also starting to do more over-the-head exercises like pullups and pike pushups etc. I have even been able to relax my shoulders while playing guitar, which has been a problem for me.
But just doing some pushups everyday might help a lot.
