im getting sick

I've been on carnivore for about 2-3 weeks and for the most part it feels great I have way more energy, feel less hungry through the day and get better sleep. My diet is milk, cheese, eggs, fruits, ground beef and steak from the supermarket.

For like the past week I wake up and have a sneezing fit, get itchy skin and I have a rash on my inner thigh thats slowly going away now. why is this happening?
