Pain in the right knee for a while(more than a year now, but got worse)

Pain in the upper right side of my right knee, it feels a little bigger than my left, no visible colouration or anything,

got worse these days i went to the gym did a routine for about a month and 3 days and it got so bad i couldnt run without pain, even squat to get something off the floor.. NEED HELP!!

I want to continue being active and doing my sport!

I recently got prescribed a gel [ibutop] by my GP and anti inflammatory ibuprofen , but it didnt help so far

I got suggested by a known medical physician to do injections with [discus compositum], done it 1 day so far it seems to be getting a bit better with time.

The knee hurts when i extend my leg when sitting, hurts when i go down or up on a squat, and going up stairs fast or even running.
