My daughter had her four impacted wisdom teeth taken out 2 days ago. No complications and no pain during her recovery. Today, however, she said she was feeling crummy, lethargic, and achey. Now tonight she is running a fever of about 100.5 and is still feeling poorly. She is not on antibiotics- just given hydrocondone for pain--she has only taken 3 of those pills in the last two days. Doesn't seem like she has an infection because she isn't having any pain in her mouth. Could it be the flu and unrelated to her wisdom teeth extraction? Should she be on antibiotics?
