how much does ETS surgery cost to eliminate Hyperhidrosis(armpit sweat) is it safe and does it stop the sweat?

You suffer from hyperhidrosis.

First try antiperspirant like Drysol, Maxim, or Megadry.
I use Drysol to get me through the weeks and it works pretty well. (www.buydrysol.com or www.amazon.com)

If those do not help and are too costly (they only work temporarily) you should research more on iontophoresis machines.
These machines can help victims hyperhidrosis. Iontophoresis machines are costly though.

I would not recommend surgery (ETS) unless you have tried every treatment possible and that includes just living with hyperhidrosis. There are many risks involved in ETS, contrary to what ETS surgeons say. If you ever want to go through with surgery you should research as much as possible on ETS online. Then get opinions on it from different MDs medical doctors that are not ETS surgeons such as dermatologists/brain surgeons/nerve doctors. ETS surgeons subtly hide information from you to rake in the $$$. This has been done before.

I’ve read that ETS has helped people but also ruined some lives.
ETS should not be considered a cure.

Hope this helps!
Good luck with your hyperhidrosis treatments.
