I had something sting the top of my foot in the garden this past summer - since then the top of my foot has been swollen, including my toes, all the way into my ankle at times. Not painful, feels fat, alternately feels cold and hot, creepy up my lower leg, like it s a bit asleep. I ve had an ultrasound and an Xray- no impediment to the flow or anything broken. There s a slight odd shaped red spot, more like a discoloration about 3/4 inch on the top of my foot. My nurse practitioner is stumped and offers no suggestions. It s not getting better. I have no health problems-62 years old female, very active, have been on a week of Prednisone to see if that helps. So far, not better. Not diabetic. Any suggestions on what to do from here?
