2 days ago my car door slammed shut on my leg due to the car bein parked on a hill like parming lot. It hurt at first and I bruised a little bit but was then the pain eventually went away. The next day my leg felt funny and I felt discomfort when walking. I took aspirin and everything was fine until later that night. My pain began shooting up my leg and I could feel pain all over my foot. Eventually my ankle felt like it was burning. The pain continued and didn't get better when I was lying down. Today the pain increased and now I'm feeling pain in my lower back. Should I wait it out or go see a doctor just in case?
