Default "Blood Clots" in birthmark

My son is 23 and has a port wine birthmark on his side. He has 'bumps' that move across his back, through his birthmark, and across his stomach, then disappear. We think they are blood clots moving through his blood vessels on the top of his skin (but we don't really know). They are tender to the touch. Does anyone else have these? Are they dangerous?
