My brother-in-law was sent to the emergency room by his family doctor. He has liver problems. He was in severe pain. He had a fever. The E.R doctor there told him because his platelets were too low & his potassium was too high they couldn't do anything for him. They said he needed an operation but Medicare wouldn't pay for it so they sent him home. What happened to caring about patients? Shouldn't the doctor find out why platelets are low & potassium is high & fix it?
