Hi I've Used Veet Hair Remover On My Bikini Line,

Hi I've used veet hair remover on my bikini line, I then got a very bad burning sensation and 5 minutes later I got in shower and washed it off. After I got out the shower it burned even more, the area is very red and has burning pains. I've dabbed cold water on it for ten minutes and now put sudocrem on, is this the right thing to do and is there anything else I can do, or do I need medical attention!
