I have had swelling in my left ankle and up my leg to about my knee. I have had this now for about 3 months. My doctor has done a doppler to rule out blood clots and has done some blood work. They find nothing and just tell me its because I am overweight. Heres the thing I have been overweight my whole life not this big but I have plenty of overweight friends and they have no swelling in their legs and wouldn't it be in both legs if it was from that. I sure would like to know if I should get another opinion. I told the doctor that I was having other symptoms as well but did nothing not even advise me what to do to lose weight.please respond.
