I've tried going without garlic, onions, etc. in my diet, but it doesn't make a difference. I don't smell
it anywhere else on me, just my hands. I'm hypothyroid, so I take medication for that as well as Glumetza and Spironolactone for too much androgen. I wondered if it was from our water, but again, it's only on my hands. I've got all sorts of other problems, but they all have general medical reasons. This doesn't, and my doctors have no ideas, and just tend to ignore the issue.
