IT Band issue or something else ? (Read 75 times)

Been running injury free for quite sometime. Did a 15k race last weekend and 2 days later in AM when I get out of bed I experience sharp/stinging pain on the outside of my left knee. Could this be an IT Band issue or perhaps something else ?

I ran 4 miles yesterday and felt no pain during run, but last night and this morning pain is back and is worse.

Any suggestions for carido while I let this heal ? I heard if it is IT Band I heard that riding a stationary bike is not a wise choice.

I'll try searching for rehab exercises unless someone has a good suggestion.
