Excessive sweating and odor after laser hair removal treatment?

I'm nearly done with the laser treatment to remove armpit hair, it's almost all gone now but lately I've noticed I've been sweating a lot more and the odor is unbearable. I've always been sweating a bit more than normal but a good deodorant would keep things under control. Now no deodorant works, I sweat the minute I get out of the shower with a horrible odor I never had before. I even sweat while sitting down without being hot or cold. Any idea what might've happened and how can I treat this? Thanks!
