Hi sir, My age 38 female. I am having mucous problem since last year. Either I had chest infection or throat infection or ear and gum infection sometime congested nose too with cough. Doctors prescribed clarithromycin, cefixime,levofloxacin and sometime ciprofloxacin. After using medicine for 5 days or as told by doctor I got well but soon after a week or more I got again caught by mucous. Rarely 5/10 days I remain OK but the rest days I have one of the above problem. It seems medicine temporarily worked and after that mucous again start producing. Is there any treatment to sop its production. Is it a vitamin deficiency? I have taken d tries injection for 1 year regularly (1 in 1 month) prescribed by a doctor. Can you please help me I am sick of all this. I keep precautions too by not eating oranges, lemon,cold drinks etc. Even then my problem not solved. Kindly tell me which specialist I should consult, chest,or ent.
