Knee Pain - Scared of DVT or Popliteal Vein Thrombosis

The other day while shaving my legs, I felt a sudden pain behind my knee. I thought I just pulled something, and so I didn’t really think about it. Now, two days later, I’m in another city for a music festival (which requires a lot of walking / standing obviously) and the back of my knee is feeling some pressure. It’s not sharp or unbearable by any means, but it is freaking me out. Someone young (early 30s) that I know recently had DVT which turned into PE, and I can’t stop thinking that maybe I should get this checked out. But I’m also not sure if it’s like just strained. (I’m 24 y/o, female, pretty thin but frequently sedentary due to my job.) It’s not hot, there’s not swelling, and it’s not red. It’s just kind of a dull pain. I’m just looking to see if there’s any kind words (or advice) about this. Should I get it checked out or no? Does it sound like something I should be concerned about?

I just realized I put this in the wrong area. Is there any way to move it?
