Don't judge. I went to get my nails done at a local (Thai) nail place yesterday. My usual place was fully booked so I took a chance. She slipped while filing my old gels off and took a chunk out of my finger/cuticle. Without asking she chucked some powder over it to stop the bleeding, then carried on and did my nails. When I got home I soaked it in some warm water to clean it, and have left it alone. I've now got a yellow-ish scab and a bit of swelling around the area. Nothing major but I'm concerned about an infection as we leave for holiday at 5am tomorrow. What can I use (that I can buy at the airport tomorrow) to prevent any infection taking hold?
