Hi, on Monday of this week, I fell down the stairs and sprained my ankle. I had gone to the er, and the X-Ray came out negative for any breaks. It was very swollen (like an orange) on the outside of my foot. The swelling is now down to a golf ball size.. I also have been walking on crutches, because I cant really walk on it. When I lay down though, or sit down.. I notice a lot if tingling and pressure on my foot and toes.. It s very bothersome.. Anything to worry about?
