Hi, I want to give you my background: I have had a rash on the tops of both feet for about a year and a half. I went to the dermatologist and had it biopsied. They weren t sure, but said it is most likely be granuloma anulare since my sugar level was 6.1 (I am pre-diabetic with Hashimotos. My sugar level was always under control until my thyroid became messed up.) The rash on my feet has since spread a bit up my legs in spots. Here is the problem: Two days ago, my feet started to get swollen. It is hard to get my shoes on. Now I feel tingling in my feet and a little up my calf. Should I be concerned? - Karen
