<s>[INST] For the last two years I have started sneezing as soon as my body temperature changes - i.e. moving from an airconditioned space to a non air conditioned space; in the gym after exercises, The doctors prescribed a nasal spray, but that does not work all the time. Any help would be appreciated. [/INST] Hello, Welcome to Chat Doctor, First we need to identify the cause for sneeze, if it is due to any allergen mere using of nasal spray will not reduce the symptoms. If you are having any allergic manifestations or allergy to any of the allergen, you have to take oral medicines to control the symptoms and avoid the allergen causing the symptoms respectively. You need to test for Skin prick test to identify the allergen causing the symptoms, and then we can plan the further mode of treatment. Thank you. </s>
