You are suffering from Rhinitis Medicamentosa! This is due to abuse of the Otrivin nasal drops which is now causing the very problem you are using it to avoid.... Rebound Congestion. STOP USING IT IMMEDIATELY. You will suffer for a short while just like other drug addicts do when deprived of their drugs.... But use only salt buffer solution to cleanse nose. This is prepared by dissolving 2 tablespoonfuls of salt and one teaspoonful of baking soda in one glass(250ml) of lukewarm water. Use a 20cc syringe ( without the needle) to flush it in both nostrils to relieve your nasal congestion.
