I have a metalic taste in my mouth. Menstral is about to start. History: December 1st, last month, I had a fracture to my head, nondisplaced left temporal bone fracture , fluid in the left mastoid air cells and tympanic cavity, is what the report states. Because I am in the healling process, almost two months into it, I still do not have my sence of smell, hearing is good yet sensitive, taste is altered and now the past couple days I have this metalic taste. Is this common for the above mentioned? or can it be lack of deficiantcy because menstral cycle is to begin in the next day or 2?
