How long after getting stitches till I can get them wet? (i got 5 on my hand and I'm dying to wash my hand!)

Sutures and water. They can be wet within hours of having the sutures placed. As long as the water is clean - ie washing or showering or swimming pools should be fine. Swimming in the ocean or rivers/lakes - probably not ok. As far as specifics for your issue - it should be safe - just "pat" dry. And avoid rubbing.
