Basically I hit in a vein that had been working for me all day, my veins are shit so its nice to find one that works. Anyway, as I was pushing in my shot dark purple started forming around the injection area and then turned into splotches all around the area on my forearm. When I realized what was happening I quickly untied and then the purple area started swelling and turning kind of white. I don't think its an artery because my whole arm isn't swollen and it didn't really hurt pushing in. And I wasn't missing either. I don't know what happened. My arm is still numb and swollen and its been like a half hour or more. Please help. I can't find anything online.
