### input:
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.

### output:

Hi, According to me, you are suffering from Allergic contact dermatitis which could be due to your perfume. If your platelet counts are normal, you need not worry about petechial.  Main line of treatment is avoiding the causative agent, supplemented by topical and oral Chat Doctor.  So, I recommend you to visit your Dermatologist to confirm the diagnosis and to initiate the treatment. Hope I have answered your query. Let me know if I can assist you further. Take care
