My daughter is 22 years old and just graduated college. She has had flu like symptoms on 3 different occasions since this past December. Her symptoms include: fever, chills, fatigue, cough, congestion, headache, and sore throat. Her last 2 times she had more achy feeling but does not have that at the moment with this 3rd episode of flu like symptoms. The time frame is Dec 2017 for first episode, April 2018 second episode and currently experiencing her 3rd episode of flu like symptoms. My two questions, 1. Why does she continue to experience flu like symptoms over a very short period of time? 2. What next? I believe she needs further workup to figure out why she has repeated illness. We are in between pediatrician and adult medicine, should she see infectious disease, immunologist, or another specialty? Thank you for any help you can give!
