The throat gets an inching sensation and it will go only after coughing aloud. I have consulted doctors there are may its allergy. I have so many test which includes CT scan of thyrox and TB also. All the test is negative. Doctors have prescribed some allergy medicines and montek LC. But this is not helping me at all. When during medication the cough may reduce but after that it comes back. I am suffering this problem from last 3 years .Due to this I am facing alot of difficulty while talking and communicating with people .After we seconds of my conversation with others the throat gets that incing sensation leading to coughing aload./ Many times my throat gets painful too. Kindly suggest, me what can be the reasons for this and a proper diagnosis. Thanks
