Sarah Hylandis back at home after spending four days in the hospitalwith health issues that doctors could not figure out.

TheModern Familystar, 28, thanked her Instagram followers for “sending well-wishes” during her weekendin the hospital, and explained that she still does not know what wasgoing on with her body.

“Long story short, I went in because I was feeling like I was being choked from whatever’s in the house,” she said on her Instagram Story on Monday night, adding that she couldn’t breathe and had “chest pains.”

“And then I was like, maybe it’s just a coincidence, maybe there’s something actually medically wrong with me. So I went to the ER after a very long day of work with lots of makeup on, and I just got home, from Friday night.”

But Hyland said that the doctors had “no scientific explanation” for her breathing issues.

“They ran multiple tests, multiple times, and there’s nothing physically wrong with me. So. Wonder why I was there…,” she asked.

“He was texting me in the morning before I went into surgery, and we were FaceTiming the entire time I was in the hospital. He’s seen me at my worst. He was there through all of that,” she said. “I think that’s why I feel the most beautiful in his eyes, because he still finds me beautiful after seeing all that.”
