My son in law has just 3 days ago undergone a ruptured appendix with the fecal matter and pus and the blood work not good. He is experiencing fluid in his lungs so they took him off IV for a bit and got him up to walk around as his tummy is extended. They say day 5 and 7 are days to pass by and look forward to improvement, else then worry. What happens after this is 5 and 7 look bad??? Any answers I could give my daughter?
