Knee pain when deep squatting or explosive movements

About a month ago I was very ill with Nora virus, while ill I fainted while showering resulting in me to slam down quite hard on my knees. Because I was unconscious I didn’t have any muscle resistance to the quick and intense bend to my knee. Over the past month, my knee pain has persisted yet slightly improved over time. I experience significant discomfort when deep squatting (without weight) or doing explosive movements like jumping or running. I am on my feet all day for work and it doesn’t limit me too much but there is discomfort in certain positions.

I am curious if this seems to be something I can continue to recover from with at home workouts, and if so what kind? Or if I should seek professional help.
