What should you know about incision and drainage procedure?

The clinician examines the lump and surrounding skin, cleans the area, and usually numbs it with local anaesthetic. A small opening allows the collection to drain. The cavity may be gently cleaned and covered with gauze or another dressing; some wounds are left partly open so fluid can continue to escape. The procedure and wound plan vary with location and depth.

Painful skin, a boil, or redness can have different causes. Cellulitis affects spreading skin tissue and may need treatment in addition to drainage. Drainage is performed by a trained professional, not by cutting or squeezing the area at home.

Follow instructions about changing the dressing, washing the wound, bathing, activity, and prescribed medicines. Wash your hands before and after wound care, avoid squeezing the opening, and attend the planned review. Tell the clinician about diabetes, immune conditions, blood thinners, allergies, or previous anaesthetic reactions before treatment.

Get urgent help for heavy bleeding, severe pain, fainting, difficulty breathing, confusion, or fever with rapidly spreading redness. Contact the treating service if pus continues to build up, the wound edges become increasingly swollen, or pain is worsening rather than settling. A new lump after drainage also needs review.

Ask how the abscess will be numbed, whether the wound needs packing, how to clean and cover it, and when review is due. Ask whether you need additional treatment and which changes should prompt urgent contact.
