Hello, Welcome to Chat Doctor, The symptoms suggest me that you are having some infection might be of viral origin. As for symptoms started with headache and fever it may be a secondary bacterial infection which has lead to diarrhea, cough and sinusitis. I would suggest you to followers antibiotics like Autoclave, 625 mg, twice daily for five days. Steam inhalation with VapocapsCough syrup like codeneOral antihistamines. These measures will improve your condition. Thank you.
