Knee pain help!

I’m having some knee pain at the top of my dominant side knee, right above the cap. It’s been coming and going every few days and I thought it just needed a few days of rest. It started after a half marathon 2 weeks ago. Took a few days off and then went for an easy run yesterday and today it’s hurting pretty bad (maybe 4/10). I had mild pain starting out on the run but it went away after 2 mi. Not sure if I should just call it and go see a orthopedist or if anyone has any suggestions! Seeing a PT (virtually though) tomorrow for it.
