You may be allergic to the particular deodorant you are using and should simply switch to another one. If you have tried this and find you are sensitive to all deodorants you use, you apparently have very sensitive skin. If you mean it burns when you first apply then it goes away, I would not worry about it. However, if you are saying that it continues to burn after application without subsiding, you should consult an allergist and see if there is an ingredient in the deodorant that is causing a reaction with your skin. He or she may be able to test for the specific allergy and find one that doesn't cause a reaction
