I'm 22y/o male. Last month, May 20 to be exact, I've experienced persistent cough with green sputum that turns white throughout the day and sore throat. I took different medicine from herbal Vitex negundo L. to Guaifenesin but nothing works for me. So I decided to go to a hospital for a check-up, it was just 2 weeks ago. The doctor ordered some tests, I'm a little worried at that time because his initial diagnosis was APTB. My Chest X-ray result was normal but my CBC shown an elevated eosinophils and lymphocytes. My doctor prescribed me Acetylcystine 200mg powder to be diluted in half glass of water 3x a day for 7 days for liquefy the sputum, Orofar-L as gargle 2x a day for 7 days for my sore throat, Claricort (Loratidine + Betamethasone) 2x a day every after meals for 7 days and Multivitamins. He also told me to drink at least 3-4 liters of water, avoid dust and smoke (by the way, I don't drink & smoke. No vices at all). After a week my cough and sore throat was gone. But my problem is this sticky white sputum sometimes looks like saliva for about 4 weeks now. What should I do to get rid of this?
