I did my second inject today in my left delt. Well here is the thing when i get done with the inject and pulled the needle out a little bit of oil came back out the inject site not alot but i was mad i feel like i wasted some, has this happend to anyone else? and should i be worried? The needle i know was in deep enough i used my 1.5in 23g needle and had about a little more then a 1/4 in showing so it was deep enough no blood when aspirating the needle everything went good except for the oil coming out should i worry or just be pissed about a little bit of lost oil? Thanks
