Hi, My daughter is 19, at college. Just called with aches, chills, in a ball in bed . I said it s fever- rest, keep warm and/or cool, and lots of liquids. She said she has been to dr for this before (a year ago) and they said she had no fever. For some reason she has never registered a high temp on thermometers, and I ve never known why. Could mental health meds affect her temperature readings? She s been treated for depression/anxiety/OCD/ADHD since 1st grade.
