The "Rock of Ages" actor was hospitalised with Covid-19 back in March 2020 when he was placed in a medically-induced coma and subsequently had to have his leg amputated and a temporary pacemaker fitted after encountering numerous complications.
He has since also suffered two mini-strokes and a lung infection, among other issues, and fitness guru Amanda has now revealed the 41-year-old actor's blood pressure isn't where it should be.
"Prayers for Nick," she wrote. "Please pray that Nicks (sic) blood pressure gets better!"
The revelation comes after she offered a brief update on Cordero's condition, calling it "a roller coaster" and sharing, "Some days are good, some days aren't. Some things look better, some things aren't. You feel like sometimes, there's lots of hope and then sometimes, it's not as much hope."
Nick has been undergoing stem cell treatment, with doctors hoping to get him "stable and strong enough to have more options."
"It's monotonous and it is hard on a daily basis," said Amanda. "Very, very hard for me, I'm sure even more so for Nick, his mother, for our families, it is like... never-ending."
