If the blood was dark red it should be a vein but the effect you describe sounds like it was maybe an arterial shot. Maybe you were dehydrated enough to make the arterial blood look dark? As it was two weeks ago and isn't causing problems I'd say you got away with it. Always worth just pressing the plunger a tad before going the whole hog to make double sure it's going the right way though. Arterial shots always swell up instantly and hurt like hell in my experience. Would be very hard to not realise you were doing it.
I'm going to agree with Shambles here. If it was dark red, it should've been a vein.
What kind of rigs are you using Eagleman? If you're using something with a long needle, and you weren't holding it still enough, it might've slipped in, out of the vein, and into an artery...however, the absence of pain doesn't sound like an artery shot.
How many units did you use? How much dope did you use? How long was it since your last dose of suboxone? How much suboxone did you do last?
Knowing these answers might help explain part of this. I don't know what else would have caused the "intense heat" you felt in your hand though, that's just a mystery to me.
If it was weeks ago when this occured, you're likely fine. However, I'm sure there are some IV complications that would take weeks or months to ensue before you would know about them (I don't know what they would be personally, but I'm sure that they exist).
Most artery shots cause problems within hours to days, not weeks though, so if it "was" an artery shot, then you should be fine. I can't say for sure 100% though, it'll be interesting to get djsim's opinion on this one.
This thread could be merged into the IV Complications thread if a mod cares to do so.
LOL
Looks like leftwing beat me to it!
Fair enough, my apologies, it's just something that's so alien and intense to me. Also dislike needles, I hate it when you go to the doctor for your yearly and they pull blood out of your arm, the vein on the inside of your elbow you know? Ugh what an uncomfortable feeling...You sir are a madman :D.
Getting blood drawn is a bit less desirable sensation than IVing something.
Plus, I've seen people get THE WORST track marks from getting their blood drawn, by a doctor or Blood Services. If you're using a small enough gauge, and are injecting, know what you're doing, etc, then it's a lot less noticeable than when you go to the doctor's.
