The paper topic is a case study, not an essay. There are 5 questions to be answered in the case study. See the paper I ve attached. Please read the case study carefully and answer the 5 questions using evidence in the literature to support your answers. References have to be no more than 6, and in APA format, with the page number next to it so I can double check it. Do not write the paper in the APA format, use a regular format, but list the references in the APA format, and give me a separate page where you list the references in APA format.Do not use wikipedia or webMD. Use references/literature from PubMed, Clinical Pharmacology and Cochrane Library only. Give me an introduction, and a conclusion. No plagiarism.Just a side note for the case study. I want the writer to know that for women, having steady estrogen levels improve headaches, however experiencing estrogen levels that dip or change can make headaches worse.
