LymeHQ · Urgent Guidance
When to seek urgent care
Most tick-borne illness is handled in an ordinary appointment. Some of it is not. This page describes the symptoms that mean you should be seen now rather than next week.
If this is a medical emergency: Call 911, or your local emergency number.
Do not wait for a callback, an appointment, or a test result. Go to an emergency department, or call an ambulance if you cannot safely travel. This page is educational information and cannot assess you. It does not replace emergency services, and nothing on it should delay you calling them.
If you're thinking about suicide or are in crisis: call or text 988 (Suicide & Crisis Lifeline, US), or chat at 988lifeline.org (opens in a new tab).
If you found a tick, note how long it was attached. Your clinician will ask. Start at step 1 of “I found a tick”.
Tick-borne illnesses are treatable, and the danger is delay. Several of them — Rocky Mountain spotted fever most of all — get much more serious over a matter of days, which is why clinicians start treatment on suspicion instead of waiting for a laboratory result. If any of the following applies to you, be seen today. You do not need to be certain, and you do not need to have found a tick.
Get seen immediately if you have
Any single one of these is reason enough. They are not ranked, and this is not a checklist to score yourself against.
High fever with severe headache after a tick bite or outdoor exposure
Rocky Mountain spotted fever and other rickettsial illnesses can escalate quickly, and clinicians treat on suspicion rather than waiting for test results.
A rash that starts on wrists or ankles and spreads inward
This distribution is characteristic of Rocky Mountain spotted fever. A spotted or pinpoint rash appearing alongside fever is a late sign, not an early one — do not wait for it before seeking care.
Confusion, disorientation, severe neck stiffness, seizure, or new weakness
Signs the nervous system may be involved. Powassan virus and neurological Lyme can both present this way, and encephalitis is a medical emergency regardless of cause.
Sudden drooping on one side of the face
Call 911, or your local emergency number. A stroke can look like this, so don’t assume it’s Lyme.
Fainting, chest pain, shortness of breath, or a very slow or irregular heartbeat
Lyme carditis can disturb the heart’s electrical conduction. It is uncommon, treatable, and dangerous if ignored.
Air hunger, drenching sweats, or dark urine with severe fatigue
Can indicate severe babesiosis with red-blood-cell destruction, particularly in people without a spleen, who are immunocompromised, or who are older.
Swelling of the face, lips, tongue or throat, or difficulty breathing after eating
Anaphylaxis, which can occur with alpha-gal syndrome hours after eating mammalian meat. Use an epinephrine auto-injector if one has been prescribed, then call 911, or your local emergency number — even if symptoms improve.
Any suspected tick-borne infection during pregnancy
Do not wait to see whether symptoms settle. Contact your obstetric provider or urgent care the same day.
What to tell the clinician
Tick exposure changes what a clinician looks for and what they treat empirically, and it is the detail most often left out. Say it early and say it plainly — bring this list with you if it helps.
- That you were bitten by a tick, or were somewhere ticks live — even if you never saw one. Most people with tick-borne illness never find the tick.
- When the bite or the exposure happened, as precisely as you can.
- Where you were geographically. Which illnesses are plausible depends heavily on region.
- How long the tick was attached, if you know, and whether you still have it.
- When each symptom started, and which came first.
- Whether you have had a fever, and how high.
- Every medication and supplement you take, including anything you started recently.
- Whether you have had your spleen removed, are immunocompromised, are pregnant, or are being treated for cancer.
Removing a tick, and the month after
If the tick is still attached, take it off now — do not put that off until someone can do it for you. Removing it promptly matters more than removing it perfectly.
- Grasp it as close to the skin as you can — clean fine-tipped tweezers are best, ordinary tweezers or your fingers will do.
- Pull steadily away from the skin, without twisting or jerking. If the mouthparts break off and will not lift out easily with tweezers, leave them alone — skin pushes them out as it heals.
- Clean the bite and your hands with soap and water, rubbing alcohol, or hand sanitizer — then check the rest of your body. Where there was one tick there may be another.
Afterwards, three small things do most of the work: write down today’s date and — if you know it — how long the tick was attached (your clinician will ask); keep the tick, as above; and watch the skin over the coming weeks. CDC on when the expanding rash can appear:
The rash: “Begins at the site of a tick bite after a delay of 3 to 30 days (average is about 7 days)”
