Several years ago I was told I had phlebitis in my legs and that the redness and swelling was from the inability of the valves in the veins in your legs to push the blood back to the heart. Keep your physician informed and keep your feet elevated when you are resting. I have since had 3 blood clots and 2 of them moved to my lungs. Keep a dialog open with your doctor so that it does not progress without your being aware of what is going on.
