My son has an extremely stuffy nose, low grade fever, headache. he has allergies and have been increasingly stuffy for the past several days. i suspect he has a sinus infection.

URI: Presence of low grade fever indicates an upper respiratory tract infection which is most likely viral at this time. In my opinion,antibiotics are not yet indicated unless symptoms have exceeded a week or are worsening. Treatment now would be resting, drinking adequate fluids, taking Tylenol and using a nasal decongestant spray according to instructions.
