Hi I am abdelrahman 32 years in egypt, I have been coughing for more that 4 week going for 5th week I do not know reason, I took vitamin c and zinc vitamins also antibiotic did not work, I cough when I talk if I been expose to cold air or drink coffee or change position, no mucus, I do not cough when I sleep, I have pain in throat, no fever no other symptoms at first there was like pain in back of head headache.

Dear Mr. lybrate-user, the best suggestion is to consult either an ent surgeon or a pulmonologist (chest physician) any cough for more than 3 weeks need to be thoroughly investigated. It can come form many reasons. A dry throat due to gerd can cause cough or even a lung infection can cause cough. Even more serious causes need to be ruled out. A detailed assessment of your symptoms is needed to suggest the appropriate treatment for you. Antibiotics are always not the solution and best to be avoided until under medical supervision best wishes.
