Agree that its normal but disagree about icing. For me, bad spots were rare and the ice on my stomach was significantly more unpleasant than the shot itself.

Perfectly normal. Sometimes you just hit a bad spot. If you're not icing before and after, I'd recommend that. It shrinks the capillaries so you're less likely to hit one, and then helps to reduce bruising after.

I have been taking lovenox for a couple of weeks with no side effects but this morning the injection site bled and now there is a little bruising and a hard lump. Maybe I strayed too far from the belly button? Is this normal?
