Fat Hand

So the IV in my left hand became occluded this afternoon. I woke up from a nap with my hand just throbbing.  When I looked down it was about twice it's normal size.  The technician, Kyle turned off the machines but then I had to wait a fair bit for Nurse Susan to come take the IV out and put it in my right hand.  Such a weird thing, I never even knew something like that could happen.  She said it will now take a couple days for the swelling to come back down.  Ugh!  It hurts a lot and is quite tender to the touch.  What would've happened if I hadn't noticed this?  Would my hand have just kept on swelling until it exploded?  I'm tired of being poked and prodded and I'm ready to be home.  I can't wait until all of these needles and wires are OUT of me so I can get a shower and feel like a real person again!
