What the terms mean

Serous=clear/yellowish normal fluid. Sanguineous=bloody. Purulent=pus (often infection). Periwound=skin around the wound.

This tool supports—not replaces—professional judgment. If you see fast-spreading redness, red streaks, fever, confusion, very bad pain, or a foul smell that’s getting worse, seek urgent care. For gentle daily care, keep the wound clean, moist (not wet), and covered with a non-stick pad. Avoid hydrogen peroxide or alcohol on open wounds.
