Some knee issues again

This past Saturday, I ran 3.3 miles in Hampden. I felt OK for the first mile, but in the second one, I felt a little bit of weird sensation in my left knee of all places. It was the same type of issue I felt in the right knee when dealing with the IT band. Well, upon waking Sunday morning, I had a bit of pain across the anteriolateral part of the knee... uh oh. It was a little twinge, and exactly like I used to feel in December when all these issues started. I am debating a run today, just 2 miles, to see if I can repeat the issue... sounds like a stupid thing, but as an engineer, the first step is often seeing if you can repeat the problem. Or, I may just do some exercises and wait until I see the PT on Tuesday.
