Reason for a thick yellow, bad tasting mucus nasal drainage-

Hello Anon

Thank you for writing.

There could be several reasons why this is happening.

You may be experiencing post-nasal drip.

Excess mucus production causes post nasal drip. The treatment will depend on the cause of the excess mucus production.

If it's caused by a bacterial infection then antibiotics are used for treatment. If its caused by a virus or sinusitis or allergies, then antihistamines and decongestants are helpful, as well as nasal sprays. In some cases the use of steroid medications may be necessary.

Additional options for relief include the use of mucus-thinning medications and/or using a nasal irrigation tool such as a neti pot which flushes out the mucus. Using a humidifier or vaporizer to increase moisture in the air can also help.

Finally, it can help to learn more about the root cause of the post nasal drip and take steps to prevent it. For example, if the cause is allergies, then taking steps to combat allergic reactions could help.

You may have a sinus infection or some sort of bacterial infection in this area too. The National Institute of Allergy and Infectious Diseases noted that in 2009, about 31 million adults reported having a sinus infection, also called sinusitis, which has several symptoms in addition to the nasal congestion. The duration can be up to four weeks (acute sinus infection) to more than 12 weeks (chronic sinus infection).

People suffering from a sinus infection can do some home remedies to help reduce the congestion from the sinus infection. For example, MedlinePlus noted that inhaling steam, such as from a shower, two to four times during the day can help with congestion. Using a humidifier and spraying with nasal saline may also help. Other home remedies that may alleviate the nasal congestion from a sinus infection include placing a warm and moist washcloth on the face multiple times.

You will need to seek medical care to know exactly what's wrong.
Best,
