How can one determine that there is a tick in the body? - briefly
A localized red bump, itching, or a tiny disc‑shaped lesion at the bite site signals a concealed «tick». Gentle palpation often reveals a firm, raised nodule beneath the skin.
How can one determine that there is a tick in the body? - in detail
Detecting an embedded tick requires systematic examination and, when necessary, medical imaging. Visual inspection of the skin surface should begin with a thorough search for any attached arthropod. The examiner must:
- Spread hair and examine the scalp, neck, armpits, groin, and behind the ears.
- Look for a small, dark, oval-shaped object partially or fully embedded in the epidermis.
- Use a magnifying lens or dermatoscope to verify the presence of a mouthpart or capitulum protruding from the skin.
If the tick is not visible, secondary signs may indicate its presence. Localized erythema, a raised bump, or a persistent rash around the bite site suggests an ongoing attachment. Systemic manifestations such as fever, malaise, headache, or muscle aches can accompany deeper penetration or pathogen transmission.
When physical examination is inconclusive, imaging techniques provide additional confirmation. High‑frequency ultrasound can reveal a hypoechoic structure within the dermis or subcutaneous tissue, distinguishing it from surrounding tissue. In rare cases where the tick migrates deeper, magnetic resonance imaging (MRI) may identify a small, well‑defined lesion with characteristic signal intensity.
Laboratory analysis supports diagnosis when infection is suspected. Serological testing for antibodies against tick‑borne pathogens (e.g., Borrelia, Anaplasma) and polymerase chain reaction (PCR) assays on blood or tissue samples detect microbial DNA, confirming exposure.
Professional removal should be performed with fine‑point tweezers or a specialized tick‑extraction tool, grasping the tick as close to the skin as possible and applying steady upward traction. After extraction, the bite area must be cleansed with antiseptic, and the patient should be monitored for signs of infection or delayed allergic reaction. Follow‑up consultation ensures that any emerging symptoms are addressed promptly.
