I am new to this group. I also had hyperhidrosis. Excessive sweating in my underarm is so annoying, and sometimes it cause bad odor, too. I went to my dermatologist. First the recommended clinical strength deodorant then drysol, but my skin super sensitive. I could not use it. Then they gave me prescription medication (oxybutynin). Also I don't like to take medication so I asked the doctors suggested another treatment. He recommend Miradry. I was wondered if any one had done this before. Does it really work? What is the difference between Miradry and endoscopic thoracic sympathectomy (ETS)?
