Injury strikes

Well, just when I thought I was all set, I had a setback this morning. Last week, right at the start of a treadmill run, I noticed a little pain in my right knee, that went away as I warmed up (within 2-3 minutes). Noticed the same little pain this morning (not noticing it Saturday or Sunday, mind you). It seemed to get better, then suddenly it went completely away and my knee then felt cool and wet, like something was dripping on it. Yet it was completely dry on the outside. NO pain, just the cool/wet sensation. And it's continued all day.

Sooo, I'll be visiting the physical therapist tomorrow at noon.
