SO sent in for surgery

Not baby related but my fiancé was having pain on the right side of the abdomen that wasn't going away. He went to the doctors this morning and they sent him into surgery right away to get an appendectomy. He just got wheeled off to the operation room now. They're not 100% sure it's appendicitis because the ultrasound didn't show anything, but blood work came up positive. Even though it's a standard surgery I'm so nervous ? because there's always risk with being put under and cut open. I'm also hoping it's not something worse or different. Send good vibes our way !!!!
