Harm Reduction strange reaction

[Milligan81d]

just succesfully injected some camfetamine into the back/top of my thumb, i know have a pins and needles sensation on the heel of my hand and travelling about 3-4 inches along my wrist, the wrist area has swollen up slightly and gone a strange blotchy colour, similar to how a bad nettle sting would look. I am an experienced shooter and there was no miss at all.........
Anyone with any ideas as to what it could be?? could it possibly be an allergic reaction???

thanks in advance

Either you hit an artery and fucked your hand up, or it's just vasoconstriction from the camfetamine.

Apply a hot compress and see if the swelling goes down; if it doesn't, see a doctor.
