hey, i jst had the operation. its called endoscopic thoraric
sympathectomy. i warn u first, before u go for the operation, do
not go to the gym to train ur chest muscles. i did and my operation
had complication, which is very rare, due to excessive
bleeding.
there's definitely compensatory sweating, u will sweat more in
other areas, bt the palms wouldnt sweat anymore =) its feels now so
soft, warm and dry. last time used to be very cold in air-con rm,
and sweaty outdoor.
