Chemical Burns from Veet

Christy
So I used Veet on my legs the other day, I left it on for 7 minutes, and ever since my legs have been super itchy and have red spots and like a rash or chemical burn. I have no idea what to do about it. I've used corn starch and hydrocortisone cream to relieve the itching, but it only works for a little while, and I've taken Benadryl and used aloe as well. Nothing is working. And it's not getting better. Should I go to the doctor at this point? Or wait it out?
