The other day I was running and added some running of the bleachers to my routine. Since then, alittle over a week, I have been unable to run. Walking is okay, though was difficult at first. I did bike ride about a week later and that didn't cause any problem. I thought it might be an inflammation of the itb. The strangest part is that there is a black and blue circle on the outside of my knee. Anyone know what it may be and what I should do?
Thanks.
