Got my shot today and I think the new nurse screwed it up, I'm in pain and never have been before and I've had a it a few times before so u know I'm used to it, it just doesn't feel right. I know she was fresh out of school because I heard her say in a non joking way to herself "I'm pretty sure this is where it goes" and her dumenor gave off a nervous I have no idea what I'm doing vibe. Oh well, I guess we'll know in a few months.
