post injection

i injected some eq in my glute, pre-cleaned the site, aspirated, and everything seemed fine, later on in the day i noticed a small red mark where i shot at. not red like a sore but almost like a blood blister. its not raised at all, or puffy, but i've never had anything like it before. this is the first time i've had to stick myself in the left glute as i normally have a buddy do it, so i'm sure my hand was less then steady, does this sound like anything to worry about or just simple tissue damage?

sounds like you have gone through a vein, you will be fine just keep an eye on it.
