Recently my sister get diagnosed with perianal abcesse and had a surgery. After the surgery she treated with oral medicines CLAVAM XR antibiotic. But in the pus culture report it came up that amoxycilin is resistant for E.Colli so after having 10 days of Clavam she is now taking Cifran 500 twice a day. But recently during the night time only she is having a mild fever of 99 to 100 degree F. Is it normal to have mild fever in this condition? She is also taking sys bath with betadine regularly and the wound is healing accordingly. Please advise. Thank You.
