I'm currently on my fifth cycle, I was doing my 5th injection today, I hadn't hit any veins till today. I had the needle 3/4 in and before I was even all the way in my shoulder pulsed, so I took it as a sign and pulled out. I processed to grab a new needle and moved slightly up and to the right of the original injection spot. This time I went all the way in and as soon as I aspirated my shoulder pulsed again and I started to leak blood. Is this normal? is my shoulder currently sensitive? I still need to shoot today should I just keep trying different spots on the same shoulder, since I pinned my left shoulder 3 days ago?
Edit: Pinned successfully on the same shoulder, just feeling shitty :/
