Can someone help with my rash ?

okay well i used to get this skin rash when i used a face product with benzoil perozice *example. Acne products* (spelling is prob wrong) because i was allergic to it and i found out the hard way lol and i havnt been using anything with benzoil peroxicde and im not allergic to anything else and i havnt been doing anything new except im on herbal-1 with my mom, and were taking the same pills and she hasnt got this rash so i dont think its that but i dont know what its causing it and how to make it go away, its been 2 days my mom thinks its from eating too many eggs because i eat 2 a day and make scrambled eggs.my grandma told me to put calimine lotion on it and i did but it didnt help and then i found this cream that the doctor gave me when i had the rash from the benzoil peroxcide and i put it on my face and the rash on my face is gettng better but not its spredding to the other side of my face my arms, the front and back of my neck, and i dont know what to do, i dont like going to the doctors so if you could tell me stuff to do other then going to the doctors i would appercate it, its really itchy and its like little tiny red bumps..kinda like this but not really lmfao http://www.dentistry.leeds.ac.uk/oralpath/viruses/viral%20infections/340%20images/other%20viral%20images/measles%20rash%20back.jpg
