Goofy home remedies should include the following:
Stay hydrated. Get plenty of rest. Ordinary analgesic (aspirin or acetaminophen) in case of fever. If fever persists more than 48 hours, or spikes quickly, get to the doctor/hospital.
Oddly enough, ordinary Mentholatum rub helps clear the sinus and over-the-counter cough drops are nearly as effective as syrups and less expensive. But more than anything it is Time which is the remedy.
