What is the treatment for cinus?

Depends . . .: If you have sinus congestion due to allergies, try avoiding allergen. If you can't, then you may want to consider saline nasal wash, an otc antihistamine or prescription nasal steroid. If you have a sinus infection, it's most likely due to a virus and doesn't require antibiotics, just lots of time. Check out http://www.Choosingwisely.Org/doctor-patient-lists/treating-sinusitis/.
