One month ago I noticed I was expercering left leg pain. First I noticed a red sore area which was raised and warm to the touch. I mentioned to my doctor abd said it was any thing serious. I put cold compress on it and then swollen went down. Now it is painful to walk and instead of being red it just sore and the area of pain is spreading. I am concerned because it hasn't gone away. What is my main concern now is that I don't have health insurance.
