What to do if…
you have sudden worsening pain, redness, or discharge after a recent procedure or dental work

Short answer

Treat this as urgent: contact your treating clinic/surgeon or dentist today for advice, because worsening pain, redness, or discharge can be signs of infection. If you have trouble breathing or swallowing, rapidly increasing swelling (especially face/neck), confusion, or you feel severely unwell, call 999 or go to A&E now.

Do not do these things

  • Do not “wait it out” if symptoms are worsening after they were stable or improving.
  • Do not squeeze, pick at, or try to drain a wound or gum area yourself.
  • Do not take leftover antibiotics or someone else’s antibiotics.
  • Do not remove dressings, packing, or stitches early unless you were specifically told to.
  • Do not scrub the area or put undiluted antiseptics/chemicals into a wound; only use rinses/cleansers exactly as written in your aftercare.
  • Do not exceed painkiller doses, or mix medicines you’re unsure about (especially if you have other conditions or take regular meds).
  • Do not drive yourself to A&E if you feel faint, confused, very sleepy, or have severe facial swelling—get help.

What to do now

  1. Check for “go now” emergency signs (act immediately if any apply):
    Call 999 or go to A&E if you have any of the following:
    • Trouble breathing or swallowing, drooling, or a sense your throat is tightening
    • Rapidly increasing swelling of the mouth/face/neck, or swelling affecting an eye/vision
    • Blue/grey/pale/blotchy skin, new confusion, slurred speech, severe breathlessness, or you feel suddenly much worse
    • Uncontrolled bleeding from a dental site or a wound you cannot stop with the instructions you were given
  2. Contact the right place for same-day clinical advice (in this order):
    • If it’s after surgery/medical procedure: call the post-op number on your discharge paperwork (ward/clinic, day-surgery unit, specialist nurse line, or on-call service). Tell them: “worsening pain + spreading redness + discharge” and whether you have fever/chills.
    • If it’s dental: contact your dentist/oral surgeon. If you cannot reach a dentist promptly, use NHS 111 (online or by phone) for urgent dental triage and arrangements.
    • If you cannot reach any treating team and it’s not dental: use NHS 111 for urgent clinical advice on where to be seen today.
  3. Gather the key details before you speak to anyone (takes 2 minutes):
    • Your procedure/date and where it was done
    • Current symptoms (where, how fast worsening, colour/amount/smell of discharge)
    • Your temperature if you can check it, and any chills/shaking
    • Any medicines you’re taking (including antibiotics, painkillers, blood thinners), and any allergies
  4. Make the area safer while you arrange care (follow your aftercare first):
    • Keep hands off the area; wash hands before touching any dressing.
    • If you were given wound/dental aftercare instructions, follow those exactly until a clinician advises otherwise.
    • If there is a dressing, keep it clean and dry unless you were told to change it.
    • For dental sites: avoid poking the area with fingers/tongue; avoid smoking/vaping (especially after an extraction).
  5. If you’re higher risk, lower your threshold for urgent help:
    Seek advice sooner (same day) if you are immunosuppressed, have poorly controlled diabetes, have a prosthetic heart valve or certain serious heart conditions, are pregnant, or the procedure involved an implant/prosthesis.

What can wait

  • You do not need to decide “what it is” (infection vs normal healing) right now—your job is to get clinical assessment.
  • You do not need to write complaints, post online, or gather lots of background information before seeking help.
  • You do not need to finish chores, travel plans, or work tasks first if symptoms are clearly worsening.

Important reassurance

Worrying after a procedure or dental work is common, especially when symptoms change quickly. Many causes (including infections) are treatable, and getting advice early is a sensible, protective move—not an overreaction.

Scope note

This guide covers first steps to reduce risk and get you to the right help fast. Follow-up treatment (e.g., antibiotics, drainage, dressing changes, imaging) depends on an in-person assessment.

Important note

This is general information, not a diagnosis. If you think you may be seriously unwell, symptoms are rapidly worsening, or you cannot get prompt advice from your treating team/dentist, use 999/A&E.
