Pain in shoulder. Possible rotator cuff problem?

Patient: What is wrong with my shoulder? 5 days ago I felt a pop in it while playing with my son. It started feeling very uncomfortable when I would move my right arm in certain directions. As of yesterday it started hurting alongside the uncomfortable feeling which almost feels like it’s dislocating, I’m not exactly sure. It starts hurting the most when I reach for something. As of now I don’t have much function of my right arm unless I don’t have to move it. What I’m feeling is at the bottom of the shoulder close the upper arm on the front of my right arm.

Symptoms: Pain, uncomfortableness in shoulder.
