Yes it's normal for bruising, a little swelling or soreness. When the needle punctures the skin it can cause some internal bleeding and a collection of blood, which is what bruising is. When I was in the hospital last year, I had a pretty bad bruise after I was finally let out. It will go away in a bit.
Alright i wasn't sure if it was common because it has been hurting quite alot and i didnt want to get to worried
Completely normal. :]
Yes, very normal.
