The Procrit shot has this little grey rubber seal, which is broken, by the syringe, that is used
to inject the Procrit with,and I have noticed that this makes the sharp point just a little bit more dull, so it hurts a bit, going in (more then the inf shot needle) Also, the Procrit burns as it goes in, but it is the least of all of our sx, it's just unpleasant for a minute.
