I tore my MCL last Sunday and the E.R doctor told me to stay off of it for at least 3 days. I did so, starting to use it in Thursday, for about 3 hours. The swelling my FOOT has encountered since then has been extreme. If I elevate and do not use it for 4 to 6 hours, the swelling recess, but if I use it AT ALL, my foot and ankle puff back up. I have been icing it, elevating it, and trying to stay off of it. What should I Do? Should I go back to the E.R? My foot f3els like an overstuffed sausage.
