Good news. I went to the Dr today and he diagnosed it as an irritated IT band. He gave me a Rx (not sure I'll fill it unless the pain gets worse) and recommended some stretches but said cycling should be fine. It may take awhile for all of the pain to be gone but he doesn't think I will make it worse by riding - "Train through it" and so I shall! Now, if it would just stop raining I'd be back on my bike.

Thanks all!
