Good advice. If I had this happen to me twice, I'd be looking for another spot. A blood vessel isn't going to squirt blood. If I'm not mistaken, blood pressure is measured by the arterial flow of blood from the heart. So for a stream to squirt, you're hitting a pressurized artery, not a vessel. I've had probably 10 thousand injections in my life and never squirted. If I did I know for certain I would hit the floor!
