What to do if…
you develop a rapidly enlarging neck swelling that makes swallowing uncomfortable

Produced and maintained by PanicStation.org Published: Last reviewed: Editorial policy USA guide

Short answer

Call 911 now. A rapidly enlarging neck swelling or worsening difficulty swallowing needs emergency assessment because it may become harder to breathe or swallow safely.

Do not do these things

  • Do not wait to see whether it settles if the swelling is rapidly enlarging or swallowing is worsening.
  • Do not eat or drink to test your swallowing if swallowing is difficult or worsening.
  • Do not drive yourself.
  • Do not delay calling 911 while trying over-the-counter medicines, supplements, or home remedies.
  • Do not walk around if you feel faint or unwell.

What to do now

  1. Call 911 now. Tell the dispatcher that you have a rapidly enlarging swelling in your neck and that swallowing is uncomfortable. Mention immediately if you have trouble breathing, noisy breathing, throat tightness, a hoarse or muffled voice, drooling, difficulty swallowing saliva, dizziness, or faintness.
  2. If you have a prescribed epinephrine auto-injector or other prescribed epinephrine device and this may be an allergic reaction, use it now according to the device instructions. Tell the 911 dispatcher that you used epinephrine. Follow your prescribed action plan and the dispatcher’s instructions.
  3. Stay still in the position that makes breathing easiest. If you feel faint and can breathe comfortably lying down, lie flat. Do not stand or walk around.
  4. If you are alone, unlock the door if you can do so safely and keep your phone with you.
  5. Only if it does not delay the 911 call, gather your medication containers or photos of their labels. Tell the emergency team when the swelling started and whether you recently took a new medicine, ate a possible trigger food, or had an insect sting.

What can wait

  • You do not need to work out the cause right now.
  • You do not need to decide whether this is an allergy, an infection, or something else.
  • You do not need to arrange a routine clinic, urgent care, or telehealth appointment before calling 911.
  • You do not need to force down food or water.

Important reassurance

Calling 911 is an appropriate response to rapidly enlarging neck swelling with swallowing discomfort. You do not need to prove that it is serious or identify the cause before asking for help.

Scope note

These are first steps only. Later decisions may need assessment and treatment from emergency clinicians or another appropriate specialist.
