I first thought this question in the case of
- the cause of dry throat after 3-day recovery of dry cough?
but then I realised that the cause of dry cough can be a general thing.
Assume the person had three days recovery of dry cough under Montelukast and codeine (tablet). He visited gym with little cardiotraining just after the catarrhal inflammation ended (no yellow mucose from throat during mornings anymore. Just after the training, he felt dry throat after very weak coughs (no codeine medication when doing sport).
I am not sure if the dry throat is caused by
- atrophy of the membranes in the throat
- or dry cough by Acute respiratory viral infection (possibly through reflex arch; cannot be sure this because no codeine medication).
Let's assume that the dry throat is caused by dry cough (although weak) because virus particle can pass easily the scarring of the mucose membrane in the throat.
I think the atrophy of the membranes in the throat are NOT felt as dry. Dry cough of the infection is felt shortly as dry. The sympaticus activity clears the mucose membrane from the throat which alleviated the pain and also irritated the scarring. Acute virus infection stimulates serous inflammation (as described here) which in the scarred tissue is felt once again as catarrhal inflammation.
So I think the cause of dry cough is catarrhal inflammation. The localisation of the inflammation is essential to determine the type of inflammation, I think.
What is the cause of dry cough?
