What symptoms does a subcutaneous tick cause on the face and how should it be treated? - briefly
A subcutaneous tick on the face usually appears as a tiny, raised lump that can become red, itchy, or inflamed, often showing a tiny puncture mark where the mouthparts are attached. The lesion should be removed with sterile tweezers, the area cleaned, a topical antibiotic applied, and the site observed for signs of infection or rash.

What symptoms does a subcutaneous tick cause on the face and how should it be treated? - in detail
A subcutaneous tick embedded in the facial skin produces a distinct set of local and systemic signs. The most common cutaneous manifestations include a small, firm nodule at the attachment site, often surrounded by erythema. The nodule may be tender or painful, and itching frequently accompanies the inflammation. Swelling can extend beyond the immediate area, producing a visible lump that may be mistaken for a cyst or granuloma. In some cases, the tick’s mouthparts remain buried, leading to a persistent, non‑healing ulcer or a central punctum from which serous fluid may exude.
Systemic reactions arise when the tick transmits pathogens or triggers an allergic response. Early symptoms of infection may consist of low‑grade fever, malaise, headache, and muscle aches. Specific tick‑borne illnesses present characteristic rashes: a bull’s‑eye erythema for Lyme disease, a maculopapular eruption for Rocky Mountain spotted fever, or a blanching rash for ehrlichiosis. Neurological signs such as facial palsy or meningitic symptoms, although rare, require immediate evaluation.
Effective management proceeds in several stages:

Immediate removal

Use fine‑point tweezers or a specialized tick‑removal tool.
Grasp the tick as close to the skin surface as possible.
Apply steady, upward traction without twisting.
Avoid squeezing the body to prevent injection of saliva.

Post‑extraction care

Clean the site with an antiseptic solution (e.g., povidone‑iodine or chlorhexidine).
Apply a sterile dressing if bleeding occurs.
Observe for residual mouthparts; if visible, seek professional extraction to prevent chronic inflammation.

Pharmacological intervention

For uncomplicated local inflammation, a short course of topical corticosteroid may reduce swelling and itching.
If secondary bacterial infection is suspected (purulent discharge, increasing redness), prescribe oral antibiotics targeting common skin flora (e.g., doxycycline or amoxicillin‑clavulanate).
Prophylactic doxycycline (200 mg single dose) is recommended when the tick was attached for ≥36 hours in regions with high Lyme disease prevalence.

Diagnostic follow‑up

Perform serologic testing for Borrelia burgdorferi, Rickettsia spp., or Ehrlichia spp. if systemic symptoms develop within 2–4 weeks.
Consider PCR analysis of the tick or tissue sample when clinical suspicion is high.
Repeat physical examination at 1‑week intervals to assess wound healing and emergence of systemic signs.

When to seek urgent care

Rapidly expanding erythema or necrosis.
Fever exceeding 38 °C with headache or neck stiffness.
New rash characteristic of tick‑borne disease.
Neurological deficits, such as facial weakness.

Prevention remains a critical adjunct. Apply permethrin‑treated clothing and DEET‑based repellents before outdoor exposure. Conduct thorough skin examinations after potential contact with vegetation, focusing on concealed facial areas such as the scalp, behind the ears, and under the chin. Early detection and proper removal dramatically reduce the risk of complications and ensure rapid resolution of symptoms.
