Well it seems like you have a bunch of different injuries present that are likely all tied into one specific event. The 2 main injuries are:
1. Fracture to the acromion. This is the top part of your shoulder. With this, you also have swelling to the ligament there.
2. Labral tear. The labrum is a soft tissue used to form the shoulder joint and prevent any abnormal movement. An injury would tear this tissue. The paralabral cyst is a common result found in labral tears.
My opinion is that you will likely need surgery to repair the damage. This will likely be done through tiny cuts made around your shoulder.
I have added a great link to help you understand this better:
