Blood blister on lower leg that won't go away? I've popped it several times, and it bleeds, but never fully heals. Looks like a mole & no pain.

Cherry Angioma. This is most likely an angioma, a dilated capillary/benign vascular tumor. They are not usually a health problem, more of an aesthetic issue. If it's small they are easily treated with a laser. Popping will just cause bleeding, but no improvement in the actual angioma itself.
