Как долго проходят укусы от блох? - briefly
Flea bite reactions typically subside within 3‑7 days, although itching may persist a few days longer if the skin becomes inflamed. Persistent symptoms beyond a week warrant medical evaluation.
Как долго проходят укусы от блох? - in detail
Flea bites appear as small, red, pruritic papules that develop within minutes after the insect penetrates the skin. The initial reaction peaks between 12 and 24 hours, when swelling and redness are most pronounced.
Typical healing stages are:
- 0–24 hours: itching intensifies; erythema may enlarge.
- 24–48 hours: inflammation reaches maximum; lesions may become raised and form tiny wheals.
- 48 hours–5 days: itching gradually subsides; redness fades.
- 5–10 days: skin returns to normal color and texture; occasional post‑inflammatory hyperpigmentation may persist for a few weeks.
Several variables modify this schedule:
- Individual hypersensitivity: highly reactive people experience prolonged itching and larger wheals.
- Number of bites: clusters generate more extensive inflammation, extending the recovery period.
- Secondary infection: bacterial colonisation can delay healing and require antimicrobial therapy.
- Age and skin condition: infants, elderly, or individuals with compromised skin barrier heal more slowly.
Effective measures that shorten the course include:
- Topical corticosteroids or antihistamine creams applied twice daily to reduce inflammation and itch.
- Oral antihistamines taken as directed to control systemic allergic response.
- Cool compresses for 10–15 minutes several times a day to alleviate discomfort.
- Maintaining clean, dry skin and avoiding scratching to prevent infection.
When symptoms persist beyond ten days, worsen, or are accompanied by fever, medical evaluation is warranted to rule out infection or allergic complications.
