Do your research and find good people to help you. Keep positive!

Sometimes you need to have someone mobilize the scar tissue around the surgery sites and that helps to get the body ready to be able to exercise again. Even after surgery, exercise is the key and after the basic ones, the progression exercises for the shoulder are absolutely necessary for maintenance almost every day.

Usually if you don't mind sharing what location you are from in the country, People on the forum can help you better with the resources you can get help from.
Or try and find a CFMT (certified functional manual therapist) trained from the Institute of Physical Art. They are best at working on the stiff frozen muscles and tissues including scar tissues. Regular PT couldn't help me and I couldn't stretch at all to do the exercises but the CFMT's were able to to help me get out of my pain and stiffness issues! I can't recommend them enough! It's worth a try!
