It's a medical condition called hyperhidrosis and typically affects the palms of the hand, soles of the feet or armpits. Just imagine parts of your body being so uncomfortably sweaty to the touch and you can understand the extreme emotional pain and anxiety people with this disorder endure every day.
Imagine being so embarrassed about your body that you don't want to leave home.
"It's really emotional. It's stressful. It's really hard," Briana Bernyk said.
For years, 20-year-old Bernyk has been keeping a secret so embarrassing, she even skipped her senior prom.
"Didn't want to go through the whole hassle of picking out a dress, so I blew it off," she said.
She didn't want anyone to see profuse sweating under her arms. The sweat from Briana's armpits is so excessive, her clothes are often drenched all the way to her stomach. After just one wearing, some shirts are stained so badly, Briana has to toss them. She wears layers and the color black to conceal the sweat.
"From sweatshirts to fancy shirts, everything I have is black," she said.
Briana's tried topical solutions, even botox injections, without success. Now, she's trying a new approach. It's a device called Miradry that uses microwave energy to destroy many of the 22,000 to 30,000 sweat glands in the armpits.
First, Briana's armpit is numbed, and then marked with a tattoo grid, which is a sort of sweat gland guide. Then Dr. Micahel kaminer gets started.
"In 90% of patients it completely eliminates sweating permanently. It's not that they do sweat at all, they just sweat like a normal person," he explained.
Four months after her second treatment, Briana still sweats, but a whole lot less. Black is no longer her color of choice
"Before I was nervous about going out, uncomfortable, always in a cover up but now, it's just exciting to go out, I can wear what I want," she said.
