Knee injury

I’ve been trying to diagnose a recently developed knee injury. I have pain towards the outside edges, right behind the knee cap. It’s most painful when I’m climbing up stairs and put weight on the leg, not so much when I go down stairs. It’s also painful when biking.

I suspect ITB, but from what I’ve read, this is supposed to be most painful when going down stairs. In any case, I’ve stopped running for now, and likely will have to stop biking to let it calm down, but any ideas/suggestions are welcome.

Thanks!

Yeah, go see a docter. Seriously. Knees (and back) aren’t something you want to mess with because you could have lifelong implications from them. This is coming from a guy that has genetically bad knees and I have had two patellar dislocations.
