Hello, I’m female 30. Never before had problems with sweating, it was like after 30 minutes running my sweat doesn’t stink. Last 2 months I have problems with stinky sweat under armpit, but just under one left armpit, under right one is like before, no smell. I’m conserned why is that happening. No matter how much deodorant I put, after few hours under left armpit it smells like onions.
