The good news is that it can be managed successfully with botulinum toxin.  Neurotoxin treatments works by blocking the nerves responsible for activating your sweat glands.  When you receive neurotoxin injections directly into the area of your body that excessively sweats (i.e., underarms), your overactive nerves are essentially paralyzed.  When your nerves can’t signal your sweat glands,  you no longer sweat. However, this is not a permanent solution and retreatment is necessary ever 4-6 months.  Fortunately, it is may be covered by your extended health plan.
