I dont have any of those symptoms, the veins are just red instead of blue, i can see them under the skin.go to a doctor if an injection site is swollen for more than a few days,
if it is red or hot or tender or the skin changes colour seek immediate medical attention.
what causes that?..thanks for the informationCould be a histamine release. Sometimes that leaves the veins around the area red for a little while.
I think that is what happened, it was itchy right away. The weird part was it had nothing to do with the vein I shot the dope in, it was veins that were higher up in the arm.It is just a reaction the body sometimes has. If it is a histamine release, its nothing to worry about, it will be itchy around the injection site, and redness may branch along the veins/capillaries. Take a antihistamine if it happens again.
