Patellar dislocation - Right leg. One?

Hello, I have had my Patellar dislocated (Right leg) on 14th September while playing indoor cricket, as soon as I had a fall I have immediately moved it back to its position. 2 days later went for an x-ray (attached). Since entire knee areas had swelling, I was being adviced to put ice packs and complete bed rest which I am following regularly. Now it's 14 days since then, swelling is reduced but still there is little swelling on left side of knee area (inwards). I feel discomfort / muscle stress pull when I try to fold my leg after a certain angle. I just wanted to check how long it's gonna take for me to walk on my own? Any other advice. I haven't been for MRI (not prescribed), shall I go and get it one?
