I had a sympathectomy 10 years ago and since have had compensatory sweating in my groin area, stomach and back. That said, I had my first botox injection for groin sweat almost 4 weeks ago and it seems the sweating has moved to under the buttocks. My concern is, will this compensatory sweating continue to move around and find another place to sweat as I get more injections with botox? I was given 100 units to the area already. An iodine-starch test was done to determine the precise area.
