Male 25 Yrs, Problem with continuous flowing nose with some sticky discharge from nose & Mouth as well (Transparent Sticky Chunk, May be Post Nasal Drip) and blockage in one side of nostril (Blockage changes side every 8-10 hrs, Means next nostril blocks and blocked one opens ). I have septoplasty in feb 2018 and facing same issue from then till now, & whenever I take cetrizine, fexofenadine problem of running nose becomes good but, one side remains blocked. Sometimes, even chest got chocked due to excess mucus production and problem starts with breathing and clears in 10-12 hrs after taking cetrizine usually. Consulted many ENT's, Done all tests. But, problem still persists. Some doctors says its Allergic Rhinitis. Is there any permanent solution to this. I never had this problem from past 25 yrs, the problems started from last 8 months. Lifestyle: Most sedentary, Sitting in AC whole day. Tests: IgE Antobidy: 155.7 IU/mL eosinophil: 07% Absolute eosinophil: 0.55 * 10^6/ml PNS Water Xray Shows:- Maxillary Sinuses are Hazy (May be due to runny nose ). - frontal sinuses are normal. - bones forming sinus are normal.
