Dealing with Knee Pain: Need Advice

I was wondering does anyone else on this app deal with knee pain? I noticed for the past couple of nights my knee tends to hurt more and this morning I woke up with knee pain. Even if I’ve done nothing that entire day it just hurts My question is that is this something I should be concerned about this and what should I do in order to relieve the pain? Context: In 2017 my right kneecap dislocated of out of socket and I found out that I have a high kneecap (almost too high in order to surgery) and lose kneecaps as well. I have done strengthening exercise and strengthening exercises as well.
