A member asked:

Why does tolerance to the cefaly device increase with use? i know the manufacturer says this is how it's supposed to work. is it damaging nerves?

A doctor has provided 1 answer

Does not damage nerv: Default produces constant stim, and the body response is toIerance. Ifyou wear contacts, you might notice that they don't bother you, but they certainly did at the beginning of your using them . This is a normal body response, and does not signify any injury to the nerve.
