The surgeons seem to have varying timing in turning on the device. I have mine doing a general buzz 24/7. There is no sign of any aggravation from it and the surgical sites are healing nicely. I've got the big itch now so I am on my way.

I go home tomorrow. I will be ready but am really enjoying my stay. It has been a joy to finally get to know my youngest grandchild. Y'all take care.
