Grade: 3
Medial side of knee cap hurts... numb pain... slighlty stiff. but goes away quickly
Update: 02/07 - maybe runner's knee, friction cause by tight IT band/ weak quads
Update: 25/07 - still hurts for 24 hours after each run. Tends to get worse in the first 4-5 hours
Update: 27/07 - physio diagnoses it as plica inflammation. Requires 3 weeks rest
Haven't done much running over last few weeks, but it seems to have calmed down.
Rest!
