I have a small redish purple lump about the size the head of a nail on the back of my right knee. It doesn t bother me when my knee is slightly bent at rest, but I feel it when I straighten my leg or am on my feet for a bit. What is it and how do I get rid of it?
Hi. A small reddish purple lump about the size the head of a nail on the back of your right knee, feeling it on straightening the leg or when you are on your feet for a bit. This can be due to a part of the Varicose vein or a hematoma. I would advise you to get a clinical evaluation by a General Surgeon and undergo tests of Color Doppler with high resolution to get an appropriate diagnosis and treatment.
