Hi, in 2005 I switched from roll on deodorant to spray on deodorant and I got a rash in my armpit that itches so bad I HAVE to scratch it and it gets all red and stinky and I can litterly pull my underarm hair out by the clump with just a little tug and the only thing that with make it go away is spraying on some tinactin. As long as I use the tinactin as deodorant I am fine, but every once in a while I will try some spray and roll on deodorant and after about two days the rash will be back so I have to switch back to tinactin. Does anyone know what could be causing this rash? I want to go back to deodorant so bad, the tinactin does not keep me dry at all. Thanks
