I m female - 46, 5 5 , 138lbs.and was diagnosed with hashimotos 5 years ago. In the past two years I ve noticed my toes turn purple when sitting and often tingle. My fingersts tingle as well. I am cold most of the time. My internist dismissed it, but I am getting very concerned.My biggest concern are the circular vein patterns all over my legs. These appeared probably 12 months ago. Today my mother saw it and was very alarmed. It s not painful, but my once pretty legs, I now hide. I am afraid there is a bigger issue going on. What should I do or who should I go to in order to get a better understanding of what is going on?
