In September, it appeared that a varicose vein on my calf was inflamed. This was noticed after a long trip. I went to the hospital and was given a test for blood clots. It was negative. The doctor felt that it was a varicose vein. The u,tea sound was negative. Now, it looks like a lump formed, but it is not painful. Shoul I be. Concerned. There is no color changes, nothing else abnormal. I am a 58 year old male.
