Christina Applegate addresses health concerns after reported hospitalization

Christina Applegate returned to social media Monday with gratitude for her loved ones.

She added, "I'm taking a moment to focus on my health, but I'll be back with more to say soon enough."

"For three years, since I was diagnosed, I've been in the hospital upwards of 30 times from throwing up and diarrhea and pain," she said. "That is unimaginable, OK? They've done every test known to man on me, put so much radiation into my body from CT scans to everything else."

"My neuro doesn't - God bless her - says that's not an MS thing," Applegate added. "So, I'm sorry, there's got to be a correlation here, and I'm not a doctor. I'm not giving medical advice. I'm just saying, just think about that, OK? Because I'm in the middle of the same exact situation, and it f------ sucks, and it's scary."

"My life isn't wrapped up with a bow," she said. "People's lives, sorry for lack of a better term, f---ing suck sometimes. So I'm being as honest and raw as I possibly can."
