When I woke up this morning, I noticed as i was walking around that my knee was hurting (with no injury). I took some OTC meds for it (tylenol, ibuprofen) to no avail. It doesn't seem like it hurts when I put pressure on it while laying down; only while walking. There's also noticeable pain in the thigh above the knee.
My mind wants to jump to worse case scenario of a Sarcoma, despite there being a very slim chance of that. But I'm trying to figure out what it could be with no injury. I'm 23 with no history of Arthritis or anything. Not sure what y'all think about what it could be.
