Did any of you suddenly develop an allergy to underarm deodorant? Do you have any suggestions?

I know the routine, "talk to a doctor" but that's time and money! I'm just wondering if there are certain products I can try. Suddenly, my armpits get itchy from my deodorant. A friend told me me to try Arm and Hammer, for women but it had the same affect. I did start to put baby powder under them, which helps a little bit but would sprays help? Any recommendations would be appreciated.
