Thanks for posting the query.
There could be several reasons for bad smell in the nose and breath. It could be due to poor oral hygiene
. A second reason is a non-allergic, non-infectious inflammation in the sinuses
that can linger after a cold. A third reason is chronic sinusitis
In your case, it looks like you have developed sinusitis after cold. Inflammation in the sinuses can block sinus drainage
. This can cause the mucus to collect in your nose and sinuses. Over time this collection of mucus can smell really bad. If the mucus is thick, a nasal wash may be needed to remove it from your nose and sinuses.
Steam inhalation will help you. Do maintain good oral hygiene. You may have short-term relief from the bad smell, but it may return again if the blockage is not completely cleared. If this continues, check with your doctor to see if a decongestant like Sudafed
) would clear this blockage so the mucus drains from your sinuses. Your doctor may also recommend a prescription of nasal steroid
spray. This decreases the inflammation in your nose and sinus and the mucus production. Generally a nasal steroid spray keeps your sinuses draining better. This may prevent the mucus from collecting in your nose and sinuses. To get the most help from a nasal steroid spray use it after doing a nasal wash.
I hope I have answered your query.

Wishing you a fast recovery.
