Well, this is def a first for me
So, nothing too out of the ordinary - started my usual procedure - 18ga 1.5" spike to air line tubing into a one litre bottle with a tiny bit of vacuum applied
Out of nowhere within about one min or so of starting my vein began to swell and form something that resembles a bubble or a bulge about a 1/4" up from the injection site.
Onto the next arm - same shit, but even faster. 2nd arm's vein just began to swell
WTF?!
Out of the more than half dozen home self blood lettings I have never had this issue
