@katclub, while I am not a medical professional, I am confident in saying if you think it is a clot, it is something that should be brought to the attention of a professional (again if you did so already Tuesday). How are you doing with your swelling? Could it be that the swelling from your knee has made its way to your leg? Any pain associated with the heavy feeling?

Hi Justin, thanks for your reply.
I see doctor this Tuesday and see what he thinks. I don’t have any swelling in my calf just a heavy feeling, my knee has some swelling yet and sometimes it burns, usually when I do my bending excercise. I don’t have any pain in my calf, thank goodness!
I’ll update after my doctor appointment.
