I have spot on my upper outer left calf (right side below knee). when pressed it feels like a bruise but no bruise present. had for year comes & goes?

It may have been a: bruise that has been metabolized and calcium/ iron deposits left behind into a small bump. Or it could be a lipoma (fatty tumor) that is benign but tends to grow. Or it could be a lymph node that enlarges when there is something inflammatory in the area such as infection or trauma. If it continues to bother you, go have a healthcare provider look at it.
