Is the area swollen? How long have you had the stitches in? ...and goodness gracious, what did you do?
in the bath, you could use saran wrap or a ziploc baggie and cut out an area just big enough to fit around the stitches on your head (by no means the entire thing, hehe), and tape around the stitches to keep the water out.
The itching and burning is normal...you have stitches!

Itching is caused by the skin reparing itself and healing, so rejoice in the itching, but do not scratch the area, that would hurt the wound and slow the healing process.
You should not cover the wound/stitches all the time, maybe at night if you have a problem rolling around in bed or whatnot, or in the bathtub, of course. But, the area needs to be uncovered. If bleeding occurs, then bandage it, apply a bit of pressure, and call your doctor. Triple Antibiotic Ointment, Neosporin, and other cleansing products can be used, but are not required. Usually they will help the wound heal a bit faster, but they hurt and burn like crazy for most folks so it is easier to do without.
Heh, I'm still just wondering what you did.
I had stitches in my arm, and I have a scar going down it...it's funny lookin, My sis calls it a caterpillar.

I'm also a med student.
