Recurring urticaria (hives): start by looking for clues in these areas
When hives keep coming back, mapping out a timeline is often more useful than guessing about foods over and over.
Clues to map out
- When it starts and how long it lasts: does it settle within a few hours or last more than a day
- What you ate, what medicines you took, and whether you drank alcohol in the 24 hours before it started
- Whether there are signs of infection, such as fever, sore throat, or diarrhoea
- Physical factors: pressure, friction, cold or heat, sun exposure, exercise and sweating
- Recent changes in daily routine, stress, and sleep
Why you should not focus on food alone
Urticaria (hives) has many triggers. Food is only one of them. Infection, medicines, and physical factors are just as common in clinical practice. Long-term food avoidance based only on "I ate something last time" often fails to solve the problem and can affect your nutrition.
Preparing for your appointment
Write down when the flare-ups happen, take photos of how they look, and keep records of what you ate and what medicines you took. Bring these to your doctor. This helps them work out the type and whether tests are needed. If you have difficulty breathing, a tight throat, swelling of the tongue or throat, repeated vomiting, dizziness, or reduced alertness, call 120 (the emergency number in China) right away. Do not wait and see.
