" I guess it's actually body odor. "
What made you to arrive at that conclusion?
"i am considering taing a surgery,which remove the sweet glands in armpit and groin area."
But that won't stop your skin from breathing so there is a chance that it won't help
Please don't get this surgery. All of us with PATM seem to have some difficulties with body odor from some reason, but that isn't what is causing people to react, I can assure you.
Look into buying a natural deodorant without and harsh chemicals or metals. Also, for me, cutting down on dairy really reduced my body odor.
