Interviewer: Your leg is swollen after a long car drive. Dr. Troy Madsen, ER or not?

Dr. Madsen: Well, if your leg is swollen after a long car drive, the big thing we really worry about is a blood clot in your leg. And here, we're talking about one leg. If you've got two legs that are swollen, it would be extremely rare to get a clot that would cause both legs to swell up. There we would think about other things like heart problems or kidney problems.

So here we're talking about one leg. My advice would be to go to the ER because you want to get this diagnosed quickly. The way it gets diagnosed is with an ultrasound and if you do have a blood clot, you're going to be started on blood thinners. The thing we want to do is diagnose this because we worry about that blood clot breaking off and going to your lungs.

So the sooner you can get it diagnosed, the better. My advice, go to the ER, get an ultrasound, get on blood thinners to get that blood clot treated.
