Hello, thanks for using HCM.
A collected boil presents with pains and from what you described it seems to me that the boil is collected. Antibiotics could be helpful if there is a systemic involvement which could be manifested by fever
and poor general condition, however most boils
are localised and incision and drainage
is the gold standard for treatment. A collected boil is fluctuant (like fluid in plastic paper) and very painful. Incision and drainage is the main treatment and incision and drainage alone without antibiotics is associated with excellent results in management of boils and abscesses and is also associated with reduced course of disease and pain relieve. You need to incise the boil and drain the pus for example by applying enough pressure an squeezing. Once the pus is drained, you will feel much better. Ofloxacin
are both broad spectrum antibiotics and apparently they seem to be sensitive to the underlying germ causing the boil as your fever has gone down. However, one antibiotic would have been enough.
Best regards and hope this helps.
