I fell 2 weeks ago and hit my head should and knees. One knee got a rug burn, the other looked fine in the emergency room. They took an exray of the one with the abrasion, but would not take one of the other knee, even though I told them it was the one that hurt, because there seemed to be no swelling or obvious injury. Now 2 weeks later I have a goose egg on top of that knee and can t kneel down on it. It is getting more difficult to bend. Do I need to go to a doctor? I have an appointment this week with my neurologist as a follow up, but I don t know if he will know about what to do about it or if I should go ahead and make an appointment with another kind of doctor.
