Re: Red bumps
I had the same thing like a couple of years ago, when the stupid lady said she'd wax it instead of threadig and I was like i guess, whats the difference because i wax everywhere else anyway. I come home and a day later the redness remains, and it's dry as hell, so much so that i had to have vaseline on it constantly all the time. I think she ripped the epidermis off. I was so embarassed to set foot outside cuz it just looked so bad. It took a good 5 days to feel normal.
Always stick to threading.
I don't know what to suggest, perhaps apply some low dose hydrocortisone cream, it'll take the inflammation away.
