Embarrassing As Hell!!

Savannah
Ok so I've never been the one to have body odor, sweat a lot, or have stinky feet. But for some weird reason here lately I've been sweating constantly, and my feet literally smell like freaking Frito Lays salt and vinegar chips! It's making me very uncomfortable and self conscious. What can cause this all of the sudden? And what can I do about it. I mean obviously I take a shower everyday, use "48Hour" deodorant for men (I'm a woman) I just like mens better because it works better and mixed with my normal natural smell it smells sweet like a woman but here lately no! And also my feet have been itching on and off which is also not normal for me! Help!!
