Detailed Answer:
Hi and thank you so much for this query.
I am so sorry to hear about these constant secretions running down the throat from your nostrils and all the troubling symptoms this has caused you..
After a careful review of the information you have provided and taking into consideration your history of allergies, I think chronic
allergic rhinitis could be at the origin of this problem.
Allergic rhinitis is generally managed with antihistamines like
Benadryl and a control of the local conditions that easily provoke the attacks like
cold, dust, pollen etc. However, given the fact that just a single nostril is at the root cause of this problem now raises the suspicion of a probable complication resulting from the repeated local bouts of inflammation.
Repeated attack episodes of rhinitis can lead to polyps. Nasal polyps are excessive tissue growth in the airway passages. This causes excessive secretions that drain either to the back of the throat or to the outside. In your case, it drains to the back of the throat and is responsible for most of these reported symptoms. At ties, it also causes difficulties in breathing. If for real this is the case, no amount or remedies would be able to resolve the problem. This is even more likely because it is no longer affecting both nostrils to the same extend which makes a possible local complication more plausible.
A careful examination and probable imaging studies would be necessary to understand exactly what isn't going right in this particular nostril. For this It would be best to get consulted by an ENT specialist. At times, a minor procedure may be needed to re-establish maximum patency and minimize excessive secretions and
drainage in this nostril.
I hope you find the above information helpful and guiding. Thank you so much for using our services and I wish you the best of health. Please, feel free to ask for clarifications if need be.
Thanks.
