For both hard and soft tick bites, 0.5–2 cm red areas, papules (small bumps), or thin plaques may form at the site of attachment within 1 to 3 days. The lesion may feel hard and may be surrounded by redness. Mild swelling or blister formation can occur. The bite can be mild to severely itchy.
Necrotic (dead tissue) ulcers can form in severe cases; usually due to bites from soft ticks. Bites from soft ticks may be painful.
Specific tick species can also cause characteristic lesions such as bruising (purpura), urticaria, and ulceration.
