Check out toronto sweat clinic. They have treatment for primary hyperhydrosis surgery to cut nerves to underarms and hands covered by ohip. Or secondary hyperhydrosis they have miradry treatment which is lazer sweat removal at $1600 a treatment. Most ppl need 1-3 treatments. Also some use botox but only works for about 6months then have to redo. Personally i just get thompson tees the bamboo ones online they wick sweat away from your body and not to outter layer.
