I Injected Crystal Meth Into A Vein On My Foot

I injected crystal meth into a vein on my foot 2 days ago. After I hit I started to inject the meth and a little bit after the shot was done it started to burn around the injection site. I know I hit because I got high and there was no bubble or start of an abcess. Now like I said its been 2 days and its red around the injection site, mildly painful and seems to be getting better. Now having said that I have 2 questions #1-What would that type of semi miss, or whatever you'd call it, be classified as and #2- I have to drug test possibly 4 days after I did it. would that type of semi-miss make meth stay in my system longer than if nothing happened when I hit?
