yea i know exactly what you mean. i mean i describe my HH as axillary ie armpits, because thats the area where its the worst but honestly i have it pretty much everywhere. just like you, if its hot or im exerting myself in any way or even if im just a bit worried, my back, my trunk (belly/under breast), neck, groin, back of knees start sweating.. basically everything! and i have noticed recently that my hands are becoming sweatier as well! arghh such a nightmare!!
