The former Playboy model took eight-year-old Evan – her son from her relationship with actor-and-director John Mallory Asher - to receive medical assistance after he fell ill on Sunday and he has been suffering with a high fever since.
She posted on her twitter page: "Ugh. Evan had a seizure. We r in the ER. He's doing better. Just laying next to him. Could use prayers again right about now. (sic)"
The 38-year-old beauty updated her page on Monday (14.02.11) to reveal Evan – who suffers from autism – was still suffering a high temperature and thanked fans for their messages of support.
She tweeted: "Up all night. Evan still battling 103.5 fever. Thanks for well wishes. they were nice to read at 3 am. Kept me company. Xxoo. (sic)"
Later on, she told followers Evan was still ill but at least had the strength to make a joke.
She wrote: "Thank u for Evan concerns. He still has 103 fever. He told the ER doc, it's only candida, and stay away from my uvula.'(sic)"
Evan is now slowly getting better and he and his mother have been relaxing by watching movies together.
She joked: "watching wall-e with Evan... wishing I had a laser beam arm. would totally use it during PMS. (sic)"Read more: Jenny McCarthy would love another child
