According to various news sources, Bret Michaels is suffering from more health issues. He had kidney surgery a few weeks ago... and he's been hospitalized half a dozen times in the two week period following that surgery. Doctors had to put two stents into Bret's body.
Pete Evick, who is Bret's friend and also part of his solo band, wrote on Facebook:
"Over the last two weeks Bret was in and out of 6 hospitals throughout the Midwest. Including the incredible Mercy Hospital of Northwest Arkansas. The staff and doctors were unbelievable and took incredible care of Bret."
I'm not a medical expert, but it seems to me that Bret would be better off by taking a vacation to rest and actually heal from surgery instead of continuing to tour the country, singing Poison songs. The people going to Bret's solo shows are pretty much die-hard fans at this point anyway, so I think they'd understand if some shows got canceled.
