19, female, no medications, I was in a car accident about 5 months ago, and injured my leg. I didnt have it looked at while I was in the hospital, because I dont have insurance and assumed it would heal over time. The pain happens when i get up from sitting for a while, or bend my leg after standing for a while. The pain is in the back left of my knee, and is really sharp and spreades throughout knee and then fades after walking for a bit. Theres no swelling or anything, so I assume there are no tears and fractures. But the pain is worsening. Since I dont have insurance, is there something a doctor could definitely do?
