I am 35 years old and little overweight and I have not had any problems until now it's mainly my right one I have sprung my right ankle before it's been almost three years ago. This is my first time it's happened to me. I stay on my feet all the time at home and it's never done this until me and my family went to Ohio for the 4 of July. Could there be something wrong. Please help me I am scared because I have diabetes and other medical problems.
