Overview
What this pattern can mean.
DermAI does not diagnose.
The product provides wellness information, probability estimates, and urgency guidance. Seek qualified medical care for diagnosis, treatment, rapidly changing symptoms, severe pain, fever, bleeding, infection signs, or any urgent concern.
Hives can look dramatic but often move quickly. A key clue is that individual welts may come and go within 24 hours while new ones appear elsewhere. DermAI asks about breathing symptoms, facial swelling, medication exposure, food exposure, infection, heat, pressure, and recurrence because urgency depends on the full situation.
A scan should never reassure a user who has airway symptoms or swelling of the lips, tongue, throat, or face. The product should route those symptoms to emergency care language rather than a routine rash flow.
Visible cues
- Raised itchy welts, wheals, or plaques that may merge.
- Lesions may change shape, move, or fade within hours.
- Can appear on one area or across large parts of the body.
- May be paired with swelling around eyes, lips, hands, or feet.
What DermAI checks
- Looks for raised transient wheals rather than fixed scaly patches.
- Uses symptom notes to screen for airway, facial swelling, fever, medication, or food triggers.
- Escalates breathing difficulty, throat tightness, dizziness, or facial swelling.
Next steps
- Track timing, foods, medicines, infections, heat, pressure, and repeat episodes.
- Avoid suspected triggers when known and safe to avoid.
- Seek urgent care for breathing symptoms, throat tightness, faintness, or swelling of lips, tongue, or face.
When to seek care
- Trouble breathing, wheezing, throat tightness, dizziness, or fainting.
- Swelling of lips, tongue, face, or around the eyes.
- Hives with fever, bruising, pain, or symptoms lasting for weeks.
Choose urgent medical care over an app workflow for severe pain, rapidly spreading symptoms, fever, breathing difficulty, eye involvement, deep wounds, significant swelling, or anything that feels unsafe.
Safe self-care framing
- Photograph the rash early because it may fade before an appointment.
- Keep notes on timing and possible triggers.
- Avoid scratching and overheating when possible.
Better photo guidance
Take photos at the start of the flare and again if the welts move or fade; include any swelling symptoms in notes.
