Hi, I'm recovering from a badly sprained ankle. I did it 16 days ago. I had a cast on for 9 days then removed because I was due to fly so have a moonboot now. The swelling and bruising is very much improved now but I've noticed that when I rub the top of my foot or move my toes a lot it causes a tingling sensation in the top of my toes. Is this normal please? Do I need to go back to the doctor?
