As it is known in medicine there are exceptions to the rule. There are some rare cases in which the patient was complaining of single side hyperhidrosis. The number of operations done for single side hyperhidrosis is even more rare. From the few cases known to Dr. Reisfeld, those who were operated on for the one side developed hyperhidrosis on the other side after the operation.
If the hyperhidrosis is on the non-dominant side of the body a patient may consider not doing the operation as they are less effected.
