My daughter ruptured her appendix early August, was hospitalized 10 days and followed with several antibiotics. She had Arthroscopic surgery 9/26, and the appendix was removed along with a fecalith. There was still quite a bit of inflammation, but she s recovered well and has been back to school, with physical restrictions, since 10/3. Today she has been home from school with a stomach ache, low fever (99-100), aches, and weakness/fatigue. There s a flu virus locally - should I be concerned?
