The procedure involved numerous injections of an anesthetic with a very fine needle (it wasn't bad but that was the worst part). Once that was completed, the nurses in the office performed the pain-free Miradry procedure (thanks to the anesthetic). It took about 90 minutes total. In the 6-24 hours that followed, I did experience some minor discomfort and a fair amount of swelling. But everything was very tolerable. It's been 5 days now and I have no pain and the swelling has almost completely subsided.
Since the procedure, I've had no hint of underarm sweating, no appearance of added sweat elsewhere and no need to use deodorant. It's been fantastic! I know it's only been 5 days, but I could not be happier.
