I have to start injecting my husband tomorrow with Lovenox.  He
normally takes Coumadin but is having a procedure on Wed.

I've done these injections many many times, but he always ends up with
a lumpy purple stomach.  Per the Lovenox instructions, I don't rub the
site after the shot and I pinch some skin and hold it until I remove
the needle.

Is there any way to avoid the lumps and bruising?   Would icing the
injection site help?  Is that a good idea?  I don't want to do
anything that will interfere with the medication.
