Hello, My husband is disabled and takes medication for chronic pain. He often runs a low grade fever and often up to 102 degrees. After he has urinated, the bathroom often smells of vomit. Could this be a side effect of the Norco or Oxycontin or something else. He also has short term memory loss or confuses days that things happen on, etc. over the past year or so, could this also be a side effect? He is extremely intelligent and feels that everyone tells him he is wrong about everything if we try to correct his details, etc. Thank you so much.
