No more running miles for me the upcoming month. I'm gonna take a long rest to get rid of my knee injury. Thing is, I don't feel any pain when playing squash, but after running a mile or so a sharp pain under my knee cap appears and gets worse and worse :S.. Fatto: A few Q's - first, have you been diagnosed with anything, or found anything on the web about this? If no in both cases, Have you been running hills lately? Is this a stabbing pain on the outside of the knee that comes on quickly? If so, google IT band and see if this matches up. Good luck in any case. For me: 4 miles in the rain this mornin.
