my (right) foot is swollen 2x its orginal size, so is the rest of my leg up to my knee. went to the doctor she treated it as a sprain…then i went back and she just shrugged her shoulders. now i have a red rash by my ankle on the inside. and i have marks that look like scars from a scratch but there was never a scratch there and they are filled with fluid. i have pain from my toes to about half way up my (right) leg. its swollen so bad i can barely bend my toes. any ideas?
