So, this happened awhile ago and it stumped doctors all over the city. Even the emergency doctors: I started taking diet pills and women s vitamins. I remember it all started with going to a perfume store and putting an oil based perfume behind my ears. Later that night I had a bumpy rash behind my ears (I m have never had an allergic reaction in my 21 years of life, not even dermatitis allergies)...a couple days later I was feeling sick and spiked a fever, then I developed a rash all over my face, little red bumps. Soon in turned into a petechial rash, all across my face and neck. and some spots on my arms. I went to the ER and they took blood tests which showed my white blood cells were fine...and recommended me to a dermatologist thinking it was a contact derm problem. They said the petechial rash wouldn t have occurred from a derm rash that occurred from the oil based perfume. I also was itchy as if I had the chicken pocks. I have gotten the rash once again since then...not the petechial rash, but the little red bumps all over my face. It seems to happen when I take women s multi-vitamins. But, I m taking them again and have had no issue. What could this have been? I m a 21 year old female who exercises regularly and has a healthy diet. I have no diseases, although I do have rh- blood and ovarian cancer runs heavily in my mom s side (she passed from it). I don t consume alcohol or drugs, so that s not a possible explanation.
