A friend of mine just texted me freaking out. It seems during his Sunday morning injection he broke off a pin, at the tip and it's dissapeareed into his ass. He's in minor pain but wanted to know what to do. I told him he has to go to hospital and they'll probably take x-rays and dig it out. Has this ever happened to anyone here? Or does anyone know of anyone's it's happened to? Just want to tell him what to expect. Also, what causes this, him not going in and out at a straight angle or a faulty pin (was BP brand from pharmacy)?
