During season changes, i get cough which lasts more than 25 days , smtimes 30 days also, and continuous sneezing, occasional light fever, and once in 10 days i found blood along wth sputum. Xray done, it is normal.Doctors always diagnose it as esinophilia, get the AEC test done and after using medicine again AEC test done, improvement is there. But cough prolongs intensity reduces.and severe sneezing persists. some say it is Allergic Rhinitis, Others Bronchitis, and some say its latent Tuberculosis. Please advise. This problem is continuing fron childhood. i am 38 years old, 68kgs weight. Do u feel my lungs are weak ??
