Tonight I shot my 2cc of SUS in my butt cheek. I shot at a 90 degree in the upper quadrant of my cheek like always...pulled the needle bck after it was completely in..saw no blood and some bubbles then injected away. Upon pulling the needle out, I noticed some blood in the area where the needle meets the syringe. also the point of injection bled more than normal. SHould I be worring about injecting it in the wrong place, like a vein?
