Extreme pain with single-leg hops--why?

I should clarify that the pain occurs after the jump is executed, not upon landing nor during the initial compression phase.

STOP DOING SINGLE LEG HOPS

Possibly ITBS or tendonitis

Patellofemoral pain syndrome is not a "bullshit diagnosis"; it is a well-documented overuse injury with fairly well-understood etiology and demonstrably successful rehabilitation protocols. Perhaps it deserves a better name ("chondromalacia," though popular, is inaccurate), but it's still a real injury. The real problem is when doctors use PFPS as a substitute for "I don't know why your knee hurts."

PFPS is characterized by pain around or underneath the kneecap—not pain in the back and outside of the knee. Sounds like the doctor you saw isn't up to date on knee overuse injuries. It's hard to blame a GP for that though. In the future, don't even waste your time; just go see a sports orthopedist who treats runners.

Hopping on an injured leg is not recommended.

Most GPs know nothing about sports injuries.

That's what I wanted to do, but all the sports doctors in my network require a referral (which this GP didn't even give me) and I can't afford to pay out-of-pocket.

To those who are telling me it's unwise to do something that hurts, well, I hear you. I'm asking about it because I think it might be relevant, especially since my other symptoms could pertain to a lot of different things. Of course I don't go around purposefully causing myself pain; but when I do attempt the single-leg hop (about once a month to re-asses) it hurts.
