's hit an artery in that exact same place, probably the same one. Sometimes it can be hard to tell, especially in the extremities, through colour alone, whether or not it's an artery you're in.
On many shots swim does on veins in his hands, the blood that registers is often so pink and frothy, that normally he would pull out and apply pressure - basically treat it like an arterial hit - yet usually it is in fact a vein.
So now, no matter what the site, or what the colour of blood registered, swim simply pushes in just a couple of increments, then waits literally a second or 2, and if no pain is felt, no tingling, nothing weird,.... pushes the rest in at a speed appropriate for the size and strength of the vein.
Swim has hit arteries multiple times, including the quite large one which runs along your inner arm just below your bicep along with the vein and nerve there.
Although it is agonising, especially if you really thought you were in a vein (and then slipped into an artery) and push quite quickly and therefore get a full unit or more in before the pain starts...............fuck that's agony.
Swim's hit those arteries many times, - one of the key reasons why now he always only pushes in a couple of increments first to 'test' no matter how sure he is he's in. It's very possible to register in a vein and then push through into an artery as you inject.
Swim's never had any problems with them other than the pain however, and simply removes the needle as carefully as he can, and then sticks his affected arm straight up in the air and applies firm, (but not intense), pressure to the site with a clean cloth - as even if no bloods coming out above the skin, below it it could be, and this practice helps the recovery of the arterial puncture.
Normally a half hour later you can barely tell it happened aside from a bit of swelling. - But do keep an eye on it, and if it continues to swell and/or get more painful etc, seek medical attention. And stay away from that area for future hits, not only to help it heal, but also to prevent yourself hitting it again! - As although things are normally OK with accidental arterial hits in the arms, they're still not to be sniffed at,- they can be very serious - so treat them seriously, and do whatever you can to avoid repeating hitting them.
Arteries in the legs however are a different matter - the main one is for those who shoot in the groin, the femoral vein. Which like most big veins is accompanied by an artery. Shooting into the femoral artery can be extremely dangerous, not to mention painful, if you do, always
call 999/911 etc. - the femoral artery is one big bastard, and carries blood under very high pressure, hence why when people accidentally pierce it they often report the plunger pushing itself up.
The dangers depend on the severity of the wound caused, the amount of solution injected into the artery
, (if any), the strength of the individual and his arteries/general health, and how quickly FIRM pressure is applied to the site with a clean cloth, the leg is raised, and the ambulance arrives.
It's that that causes the many junkies to be in wheelchairs with legs ALWAYS amputated at the highest possible point - no chance of walking then.
An acquaintance of swim used to shoot in his groin, and one day was doing so in his room. He hit up, all was good, and he lay down on his bed to relax. Unfortunately, at some point during the injecting procedure he just slightly scratched the femoral artery - un-noticeable at first. Until, after about 20 minutes of lieing on his bed, the pressure of the femoral artery caused the initial scratch to rupture, and blood literally gushed to the ceiling of the guy's flat. The whole 20 minutes the guy had been lieing on his bed, the little initial scratch had been being put unde more and more pressure until, finally, it burst.
As far as swim knows, as he was living in sheltered accomodation, people heard his cries, and the ambulance arrived in time. But the amount of blood that can be lost out of big veins and arteries such as these is staggering. Just a word of warning.
EDIT: Once you've hit an artery once, no matter which one, you'll know for sure if you hit an artery again, the feeling is exactly the same, just more or less agonising depending on the artery etc.

Apply pressure to the area with some sterile cloth (or clean if that's all you can get) and keep applying pressure until the bleeding stops. If the bleeding continues, do not take off the bandaging that you are using, instead- use more and press it on top of the bandage you are using otherwise any wound might reopen.
Only if you hit very big arteries will blood exit rapidly and heavily in this pumping motion.
Hitting a small hand artery with a small gauge syringe is incomparable to hitting a femoral with a 21 or 23 gauge pin.
Hitting a nerve causes an almost unstoppable urge to immediately withdraw the syringe - swim's done it several times, it doesn't cause the intense feeling of fire shooting through your veins like arterial hits do. It's much more of an instantaneous almost stabbing pain.
