Dad had varicose vein surgery years ago he bumped his leg & now there is a bump & the dr. keeps using a needle & drain fluid is the a fix for this?

Fix available: If the lump is persisting despite needle drainage, an ulrasound of the lump and the veins looking for veinous insufficiency may reveal a more treatable diagnosis.

Yes: Trauma to soft tissue of the body can result in bleeding into the tissue forming a hematoma(clotted blood) and over time this is broken down by the body, and aspiration (using needle to drain) will often resolve the swelling, at times requiring several attempts.
