You would like to know the reason for the mucus that built up.
Mucus in the nose is built up when there is an infection located in the nose. The nasal discharge may be colored and viscous if there is bacterial infection and colorless and water-like if there is a viral infection.
Sometimes the nasal discharge may be released from the back of the nose into the pharynx often provoking coughing. Bad breath may appear when there is caries on the teeth or when the gums are infected or delicate to the touch and easily bleed.
You may consider seeing your doctor to consult him whether you may be experiencing one of the following medical conditions: nasal, pharyngeal infection or chronic sinusitis. You may also consider seeing a dentist to check up on your teeth and gums.
Please keep in mind that I am trying to provide you with medical information here. I am not able to give you medical advice online. Please contact your doctor or a qualified healthcare provider such as a dentist for further information about diagnosis and treatment options.
