So I pinned my delt tonight. Put it in the right spot in the area I always pin and have done it 20 times there by now. Aspirated and no blood at all. put in all .8ml of oil felt fine no problem. When I pulled out the needle had a stream of blood literally shoot up and out about 6 inches on the counter and a stream pour down my arm until i put my finger over it. Kinda freaking me out. Maybe I hit a vein on the way in? Because like I said aspirated and was good. Never happened to me before and kinda freaks me out. Had a few drops drip out before just nothing like that. Its been about 5 minutes and I feel ok right now. Has anyone had this happen before?
