Even the best fitting prosthetic limb can become uncomfortable when you are in a hot and humid environment for an extended length of time. I recently discovered that some prescription strength antiperspirant products had become available over-the-counter, so I gave them a try. Certain Dri antiperspirant (roll-on version), and Secret Clincal Strength antipersirant/deodorant are the two I tested. I prefer the Certain Dri; you apply it to your limb before
