What does a tick bite look like after a week? - briefly
After a week the bite typically presents as a small red or pink papule, often slightly raised and occasionally encircled by a faint halo; a target‑shaped erythema may appear if early Lyme disease is developing. Increasing pain, swelling, or expansion of the rash warrants prompt medical assessment.
What does a tick bite look like after a week? - in detail
A tick bite after seven days typically presents as a small, red or pink spot at the attachment site. The centre may be slightly raised, while the surrounding area can show mild swelling. In many cases, a clear, circular ring—often called a “target” or “bullseye” lesion—develops, with a darker centre surrounded by a lighter ring and an outer red rim. The size of the lesion ranges from a few millimetres to over a centimetre, depending on the individual’s reaction and the tick species.
Additional characteristics may include:
- Erythema: Uniform redness or a concentric pattern.
- Induration: Firmness of the skin around the bite, indicating inflammation.
- Itchiness or mild pain: Sensations may persist, though they are usually mild.
- Absence of a tick: The arthropod is typically detached after feeding; no visible insect remains.
If the bite is infected, signs such as increasing warmth, pus, spreading redness, or fever can appear. In such cases, medical evaluation is required. Otherwise, the lesion often fades within two to three weeks without scarring.
