Did you have to relocate it or was it basically ok without touching it? If it was really dislocated you could have torn the labrum depending on where the humerus exited the socket and possibly the biceps tendon if it dislocated with your arm over your head. Basically MRI for sure and probably surgery. Try to get a MRI without contrast if you can get away with it and get a 2nd MRI with contrast if they can't see what they expect but a good radiologist can see without it. The contrast is sort of like putting a gallon of water in your shoulder and then seeing if anything separates from the pressure, not good and it will increase the injury although they will just go in and fix it anyway.
If you go to 5 doctors, sports medicine guys will try to rehab it and tell you to strengthen the muscles around it, surgeons will try to cut it and fix the underlying issue and then rehab it. The surgeon will almost never reject an easy 1.5 hours of work. Neither will agree with the other so it's your decision, good luck.
If you didn't fully dislocate it, you might get lucky with some physical therapy, no heavier than 3lb at first and you are going for mostly range of motion and stability because everything is now stretched that guides the various bones of the shoulder.
Even if you wait a couple of weeks with 0 activity before you can see a doctor it won't really change your outcome or their ability to diagnose it.
