Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.
Seek urgent or emergency care for rapidly worsening illness, confusion, fainting, breathing difficulty, or swelling that affects swallowing or the airway.
Contact the healthcare professional sooner if:
Follow-up instructions depend on the abscess and how it was treated.
A clinician may arrange a wound check within a few days, especially when packing or a drainage tube was placed.
Keep this appointment even if pain has improved, because the opening can close before the deeper cavity has healed.
During routine healing, pain, swelling, and drainage should gradually decrease.
A small amount of fluid on the dressing may be expected after drainage.
Ask the treating team what is normal for the specific wound and when dressings or packing should be changed.
Recurrent abscesses deserve a planned medical review rather than repeated home treatment.
The clinician may look for a cyst, fistula, foreign material, hidradenitis suppurativa, diabetes, or another factor.
Prevention may include treating an underlying skin condition, covering draining wounds, regular handwashing, and avoiding shared personal items.
Some people with repeated S. aureus infections may be offered a clinician-supervised plan to reduce bacteria carried on the skin or in the nose.
