IM Injection, Hitting Bone?

I was giving my mother an IM injection for the Flu Vaccine at the hospital, I did the injection and felt that I hit a bone or something. I did aspirate and received no blood return and went ahead and inject the medication. The injection was a little high up, not where I received mine.

Is hitting the bone bad or something... will it cause any negative effects. I asked her if there was pain afterwards and she said not really?

I am more concerned that you were treating your mother in the hospital. Or was this at home? I agree with others about pulling back a little before administering the medication. I also believe most information is supporting do not aspirate except with just a very few medications.
