being 'really pumping'? My veins pop up like that when I am really hydrated and doing something 'active' [a loosely defined term differing for those of us who have PN and other fun things?]

They disappear when I am either inactive or dehydrated. Plain and simple?

I don't know if it's tied to Blood pressure or not, as I don't have a BP machine home access....

I really wouldn't worry unless you are getting a headache or other pains tho? With your diabetes so well under control the only thing I'd think could happen is IF you forgot to take a med or the like...

As one who gets infusions regulary, and blood tests? Hoppin Poppin veins make those who treat us VERY HAPPY! I like my health care staffers HAPPY! They are the ones who really take care of us! Hugs - j

PS Hobie - VERY GOOD PUN!
