Amy Schumer spent five days in the hospital this week being treated for a “horrible kidney infection,” the actress said in an Instagram post Friday morning. In the post, Schumer said the illness caused her to miss the opening of her new film I Feel Pretty. She also thanked her husband, Chris Fischer, and sisters for their support during her medical issue, as well as the hospital staff that treated her. “Here’s what I’ve been up to this week. I was hospitalized for five days with a horrible kidney infection,” Schumer wrote. “I want to give a big thank you to the doctors, the bad ass nurses also my husband who’s name is, i want to say, Chris? and my sisters Kimby and mol who have been by my side the whole time.” I Feel Pretty opened to $16 million last weekend — but has 34% on Rotten Tomatoes.
