I am 53 yesrd old male havingver severe throat congestion quite freauently for more than a year. I use to get soar throat and uncontrollable cough more often. Some fluid / flum comming from sinus such as nasal dripping use to get collected wiyhout going into food pipe, which in turn irritate the throat leading to soar throat condition. If I take some antibiotic and anti allergic meficine the problem will subside for a week. Once I stop the medicines it will recurr. Some times when I forcefully spit the flum alongwith saliva ( green in colour) I get blood in the spittedflum. The troat swap test done so far has no negative signs. When I was 15 yrs old one ENT doctor told that I have ceptal deviatiln lf bones. Even fro childhod I cannot drink cold drinks ice creams and even normal tap waterad I ude to get throat infection if do so. Hence I request u to suggest the coursr og treatment I should take to get rif of this problem permanently.
