1. Since my fall down our stairs (one month ago) I have been sore off and on. This past week my right leg really started to swell and both of my legs eventually puffed up like balloons. Above is a picture I took at the doctor's office while I waited. My leg hurts so bad that I can barely push down on the gas pedal. My doctor put me on a water pill for a week so that the swelling would go down, and from there we will figure out if my knee is just a simple strain/sprain or something else. I think the pain could just be from the swelling.
