The chronic cough you are having from last 5 weeks can be due to following causes: asthma
, allergic rhinitis, sinus problems like sinus infection,esophageal reflux of stomach contents(GERD),postnasal drip (Rhinorrhea).Other cause are:lung
diseases such as chronic bronchitis
,certain medications,respiratory irritants such as chemicals.
You need X-ray chest,pulmonary function test,allergy and sinus tests,endoscopy,bronchoscopy.Dry coughs are treated with cough suppressants also called antitussives. Dextromethorphan
,codeine are the common one.Other cough suppressants include glycerin and lemon and honey, which coat and soothe the back of the throat.Antibiotics may be prescribed if infection is confirmed.
Exact diagnosis can only be made after physical & clinical examination.So I advice you to make an appointment with your doctor for these tests & examination to know the exact cause & then treatment will be done accordingly.
