"Apologies for the pale white face," posted Michaels on Tuesday along with a photo. "It's the first day I've been able to fly to the kids. There is not enough thanks that I can send to the awesome fans, friends, family and medical staff for their help and well wishes. You all rock!"

Under doctor's orders, Michaels cancelled shows in Wilkes-Barre, Pennsylvania and Albany, New York late last week while he remained in hospital.

The rocker dealt with complications involving insulin shock and severe low blood sugar, along with other conditions which doctors later determined included exhaustion/dehydration/fever and the noro flu virus (Norovirus).
