Hello Pinker and to Everyone,
First off, great work, Pinker, on putting all this information in one place. This is truly helpful information and just what everyone needs.
In my case, I have palmoplantar HH (hands and feet). I’ve tried just about everything over the years, including most items listed here. But during that time, I developed a bad habit of not sticking with one thing too long, despite having some or limited success. I guess I was truly looking for a cure, in a sense. I may have to try Odaban and Iontrophoresis once more, if needed.
My story recently is that my HH used to be nearly 100% palmar and near zero plantar. About a year ago, I began noticing my plantar increasing little by little.
To make a long story short, today, my palmar has reduced, but my plantar (feet) is really wrecking havoc on me at work and when my anxiety kicks in (both feeding on each other). My feet get hot and sweaty; therefore I have to change shoes and socks, since the odor begins to develop. The more the odor develops, the more my anxiety kicks in and just exacerbates the problem.
Today, I have about 8 pairs of dress shoes (2 extras in my car) but most of them are already ruined, I believe, due to the bromhidrosis odor. I’ve spent a fortune recently on shoes and powders of all sorts to stop the smell of my feet and shoes. It has really affected me in my profession.
Recently, I just started with acupuncture (1 session so far). Also, I went to see a podiatrist today, and the Dr. recommended Lazerformalyde (10% formaldehyde)—and he said this stuff works (supposedly much stronger than Drysol) and has a perfect track record for him so far with his patients. I will try it for the fist time tonight, and I really hope this works.
My question is, have any of you tried Lazerformalyde? If so, has it worked? Also, have any of you developed plantar at a later stage, and while noticing a slight decrease in palmar? I’m now 41, and this just started a year or so ago for me.
Any advise/info. would be greatly appreciated.

Update: Day 1: Today was absolutely great

. No smell at the office. Didn’t have to change socks and shoes. Wow! Socks still felt a bit damp at the end of the day, but nothing like before. I did notice that I sweat maybe just a tad bit more in the palms, but that’s fine. I can deal with that, but not the smelly shoes/socks/feet. (BTW: my doctor who prescribed Lazerformalyde mentioned not to use this on the hands, as it can get into your eyes easily (by accidental rubbing). And it could cause very serious irritation. Anyhow, we’ll see. It’s just day one, but so far very promising results! Thank God!

I'll post status again in a week.
