Bruise on my side for no reason

My side was itching, so i look before i scratch to make sure not insesions i am touching, and i have this red/purple bruise from out of no where...I am waiting on a ride to carry me to the doctor....So i was reading the box for lovenox and it is a side effect listed...hoping i can stop the shots and everything will be ok....scared it may be something else....has this happened to anyone else?

I've never had that experience, but don't take lovenox either.  What did your doctor say?

the Doctor said it was the side effect of lovenox...had me put anti-itch cream on it and a heating pad said it will  eventually go away.
