When irritation grows used DUONASE two times {before 24-march 2 dose (1 dose = single spray in both nose) and around 31mar/01apr 4 dose}. On 4-Apr throat become heavily sore and even voice changed. On 5-Apr evening  sore throat was already there and right nostril also gets jamed.When nostril gets jamed then again used DUONASE 1 dose and got relieved also. On 6-Apr consult a chemist then on 17th consult a doctor and took medicine as they told but didn't fully relived. Present Symptoms are :- 1)when wakeup any one nostril gets jamed and then repeated sneeze. Also dried,tight & sored vocal and throat. 2)After Sneezing - nose & mouth feels with mucus & give relief 3)Very light khasi(once in 3-4 day) & after it mucus from chest and vocal box comes out. Note -During long walk or exercise or in hotday out problem minimises BUT in evening it increases and during night(after midnight) it is more.
