Help!! Knee pain

Hi! About three weeks ago my left leg started bothering me. I had mild pain from my glute down to my ankle. I couldn’t tell where the pain was originating from but after more intense pain after my last two runs- when I put pressure on my inner knee (from research I think my meniscus), it hurts.

I went on a run this morning and had to Uber home because of sharp pain. Now when walking it is sore, and pain is spreading behind knee and down to my ankle.

I’m trying to get into a PT this week (have never been or had an injury). I would appreciate any insight :)
