yes thank you. I have a small lump on the back of each of my legs just above my knees. on one leg there is a prominent blue vein in the middle of the lump though the vein itself is not bulging. there has been slight discomfort in my legs the last couple of days starting in that area and moving down my calves. the lumps themselves are not painful or warm to touch and they are not red in color. they are soft, not like a mass or a knot. also, and maybe unrelated, I have very bright blue veins all over my chest and on my left shoulder moving down my arm. also I had a random nose bleed today. I am a 34 year old male. I sit for very long periods of time so I am concerned these could be blood clots. Any ideas? Nothing at all?
