Hi, I'm new to this group. I have been tortured by HH since I was 10 years old, now 34. My hands and feet are the worst affected (dripping like a tap every waking moment) but I sweat everywhere! I descovered Oxybutynin when I was 20 and it saved my life. It decreases the sweating by about 70% but only in cool temperatures. I now live in Spain (great move, right?) and have been dreading the summer. I use iontophoresis on my feet which works if I use it for 1 hour per day constantly. I can't put my hands anywhere near it, the pain is excruciating, even on the lowest setting. I tried botox and it was a total waste of money. I was wondering if anyone else's symtoms get 1000 worse in humidity? For me it's not just sweating but my fingers and feet swell up to the point where I can't bend my fingers properly and they throb. I'M SO SICK OF THIS BULLSHIT- sorry, having a really bad time at the moment, not even leaving the house during the day. I go all winter being able to semi-control it and then I'm back to being a 13 year old ashamed sweaty teenager. I've just ordered Avert and I'm hoping it works better. Anyone have similar experience? Thanks for reading.
