Hello As you mentioned that you are having stuffy nose and sneezing continuously but NO ALLERGY. Symptoms worsen with movement of head. You got temporary relief with inhaler . All these symptoms may be due to , these reasons , these include. 1 Rhinitis :Inflammation of nasal lining membrane as this produces these sign and symptoms . Nasal itching Watery rhinorrhea Nasal obstruction Sneezing post nasal drainage Headache impaired smell morning cough ( in few cases ). When such type of patient visit my clinic I advise them to take monteleukast+ fexofenadine tablet one or two in day according to severity of symptoms . Ephedrine +saline spray in nostril also provide instant relief ( few patient feel palpitation ) . 2 NASAL septum deviation . Nasal examination is important . Optional in patient with/mild intermittent symptoms. preferably performed by endoscopy . Nasal exam may reveal the following: --Swollen nasal turbinates ---Nasal crease --Rhinorrhea w/ clear , cloudy or colored discharge mouth breathing. In my opinion consult an E N T specialist and get his opinion. Hope this information will be helpful for you.
