I have had a persistent cough with no phlem for about 4 weeks. No fever, no other symptoms. Same thing happened last year at this time lasting about 2months. My dr has me on Albuterol with a nebulizer, Flovent diskus, and a pro air inhaler. I am not getting any relief. My chest X-rays are clear and with a stethoscope all is clear. I have asked for a referral to a pulmonary dr! My internet doesn t seem concerned because she says it is an asthmatic response to bronchitis. What more can I do for relief? Will a pulmonary dr be able to do anything more?
