Ellen DeGeneres took to her Instagram to share a health update with her fans after announcing she had tested positive for coronavirus last week.

She posted a video from her home, saying she feels “100%” despite the diagnosis.

“I feel really good,” the 62-year-old television host said.

“One thing that they don’t tell you is that you get, somehow, excruciating back pain,” she added. “Didn’t know that was a symptom but I talked to some other people…Who knew? How come?”

Though the U.S. Centers for Disease Control does not list back pain specifically as a COVID-19 symptom, “muscle or body aches” is one of the disease’s symptoms. Other telltale signs of coronavirus are fever or chills, cough, shortness of breath, fatigue, headache, new loss of taste or smell, sore throat, congestion or runny nose, nausea or vomiting and diarrhea.

The CDC has listed emergency warning signs that indicate patients should head to the emergency room as well, including trouble breathing, persistent pain or pressure in the chest, new confusion, inability to wake or stay awake and bluish lips or face.
