Evil rash - butt picture warning - T's not mine
T's had this rash for over 2 weeks now. It started on her butt cheeks and has spread to her legs and arms. Its raised and becomes red when she scratches it (because is itchy). Her doctor said its contact dermatitis (an allergic reaction to something her skin came in contact with) and told me to apply 1% hydrocortisone 3 times daily. I've been doing that and its done nothing. Its actually spread. He also gave me a prescription for a stronger steroid that I'm going to fill on Tuesday if its not better by then. I've also tried my Angel Baby Bottom Balm, calendual oil, Aquaphor, and now coconut oil. Nothing seems to help.
While I'm trying to make her more comfortable and treat the rash, I'm also trying to figure out what on earth is causing it. The doctor said its not something she ate so I'm concentrating on things I use around the house. I haven't changed anything in months so I'm kinda lost. I'm starting with our laundry detergent. I already use Free & Clear detergent on our cloths & bare minimum Crunchy Clean detergent on her trainers and night time diapers. Aside from her body wash/shampoo, sun screen, and bug spray I don't really put anything on her. I clean with vinegar mostly so its not some chemical she's picking up off the floor or something.
What else am I missing? Is there something else I can try for her skin?
Here's a pic of the offending rash.
