Get emergency medical help now for severe or rapidly worsening pain, swelling, redness, or discoloration around the genitals, perineum, or anus.
This is especially important if you also have fever, confusion, dizziness, weakness, a bad-smelling discharge, or feel severely unwell.
If you feel faint, confused, short of breath, or unable to travel safely, call emergency services.
Do not wait for the skin to turn dark or for all symptoms to appear.
Do not try to drain a swelling yourself.
After hospital treatment, seek urgent help for new fever, increasing wound pain, spreading redness, darkening tissue, pus, a strong smell, wound opening, confusion, or a sudden decline in how you feel.
Contact your usual follow-up team sooner if healing appears to stop or day-to-day function is not improving as expected.
Routine follow-up is appropriate for questions about dressing supplies, gradual scar changes, returning to work or sexual activity, and ongoing rehabilitation.
