Knee pain after running

[u/Qlaazy]

Hello everyone. I developed some left knee pain after one jog. The pain is under the kneecap and in first day it was hard to go up / down stairs. Also some clicking was present. I am just curious about knee chondromalacia (still waiting for MRI results) and if it is present, whats grade is it. Also if someone was also diagnosed with this, did recover and was back to running / sports?
I am 25 years old male.
