Hi. Thanks for your query. Noted the history about your boyfriend having lightheadedness, tinnitus, vomiting and skin smelling even after shower. I would advise him the following in such a case: - CT scan of the brain and the mastoids for inner ear. - Clinical evaluation by an ENT and Neurologist to have a clinical examination and probable diagnosis. - Further tests of blood, urine and others as may be necessary after initial investigations to decide the cause and to get a proper treatment. - Smell from the skin is basically dependent upon many factors: the foods, beverages, the deodorants used, and some medical conditions. Get a clinical judgment, permutations and combinations of the factors I have mentioned and he will be fine.
