Just curiuos how much blood is considered normal after an injection. Sometimes there is none. Other times just a dot or two. However, yesterday after I inj. a stream of blood ran down my leg. Now, I have been asperating and there was nothing in the needle so I thought I was in the clear. Then after I pulled the dart out, I had a stream of blood run down my leg. Any thoughts? Did I pass though a vein maybe? Also when asperating, if you are in a vein you will see blood in the dart when you pull back right? Just want to make sure as some of the post I have read caused a little scare. I am not spot inj, either. Just in the rear. Any information regarding inj and saftey would be much appreciated
