My (as of March) 18 year old son - started 2018 off sick. No kidding - 1 January - in the doctor's office (Patients First) for fever......
For the first 3 months - it was one thing after another....just now, he's FINALLY getting better.
Yes, fevers CAN happen with allergies. As her body is introduced to new allergens, her body can get a fever trying to fight them. Get her checked for allergies.
Good luck!
