I had stitches on my back for Lypomas. They keep opening up. Can I drive a school bus like this?

I would say, ring your doctor, and check with them. If the wound has healed, then yes, you can drive it, but if not, and the stitches are opening up to an open wound, then no, certainly not, you could get an infection. Just ring your doctor right now to double check with them. :)
