Hello, In my opinion, the abscess secondary to surgery is an infected abscess. You should get it treated with antibiotics. And you said she has already received antibiotics. Fatigue, malaise patient can develop because she wasn t able to eat properly during this period. Seeing a doctor in person is very important in all these conditions. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Saba Afreen R
