thanks for offering me this opportunity. My wife is suffering from persistent cough for amost 5 months. she met several doctors and recieved various treatment but the her situation remained un changed or change slighty. Her main complain is throat itching( specifically she complain from itching below her tongue) which trigger a convulsion of cough, she didnt have heart burning but feel discomfort from her stomach. She had X-ray and it was clean, she also had H.pylori test (stool) and it was (-ve) . The first diagnosis by the E.N.T especialist is she had sinusitis , but the second diagnosis by another E.N.T Especialist was viral inflammation in the pharynx. Through her follow-up she recieved medicines like Protect, G.M. PROTAC,Physiomer,Rhinocort.
