If you're ready to go back to work Vexing, and the area is visualy healthy, then put some barrier cream on it and cover with a gauze, tightly taped. Keep the barrier and tape away from the actual wounds.
Make sure you take spare gauze and tape with you. Perhaps some moist wipes. You can get surgical wipes from the pharmacy. Though baby wipes are just as good. Just remember, social hygine.
Try it out for a few days before you go. Just so you can know what sort of problems to expect.
