When should you see a doctor for hives?

You should see a doctor for hives in the following conditions

1. If they are accompanied by difficulty breathing or swallowing, or swelling of the face, tongue, or throat.
2. If they last for more than six weeks (chronic hives).
3. Additionally, if you have a fever or if the hives appear after taking a new medication, it's best to consult with a doctor.
