[|Human|] I have had a persistent cough for 4 weeks and was on prednisone.  My cough improved a bit with a cough medicine but I am still coughing.  I was put on more prednisone and antibiotics.  I dont feel much better and my right ear feels blocked occasionally.  Any suggestions as to what might be causing this.  I am asthmatic.
[|AI|]  Hello, Thanks for the query to Chat Doctor. Forum. Cough from 4 weeks, right ear blocked, asthma, As Eustachian tube (in ear have direct connection with throat so any infection of allergy first block this tube) has direct link with throat, so blockage is very common in this area due to allergy. Prednisolone is the most potent steroid, and it should be used only in emergency cases. Anyhow, I suggest you please consult a physician and get his opinion regarding cough, which is from 1 month. May be due to, Tuberculosis, allergy,lung infection with allergy. X-ray chest pa view is necessary. Hope I have answered your question. If further any question I will help. Good luck.
