This is Dr Basu, experienced Internal Medicine Specialist.
I am here to address your concerns and provide great service.
Sorry to hear about your symptoms.
The increased size of shoulder joint along with restricted movement suggests likely dislocation of the joint anteriorly.
There is also significant rotator cuff tear.
Rotator cuff is a major muscle group to support the shoulder joint.
Its rupture will weaken the shoulder and also cause visible swelling.
Hence you will likely need surgical repair after further evaluation by orthopedic surgeon.
MRI scan will be required.
Meanwhile, you can use arm sling to immobilize the shoulder.
Ibuprofen and warm compress may help with the pain.
It was my pleasure to help you today.
