How Long Does Persistent Deep Cough With Congestion Take To Cure?
Information
Detailed Answer:
Hello,
I think it is time for you to go back in to be seen.
Most respiratory infections start out as being caused by viruses. It can take up to 3 weeks to clear a viral bronchitis or sinus infection. Sometimes longer.
However, if it continues for longer than that, we need to revisit the infection as sometimes a secondary infection develops with bacteria. Typically then there is also fever and discolored mucus. But not always.
So, I think it's time to go back in to be seen, even if the chest X-ray was clear 4 weeks ago.
If the chest congestion seems to be coming from drainage from sinuses, consider a decongestant (oral pseudoephedrine) and steroid nasal spray, which may decrease the drainage.
I hope you are feeling better soon!
