Bed Bug Bites vs Hives: Clues From Timing and Pattern
Bed bug bites and hives are both itchy red bumps that can appear overnight. Bed bug bites are fixed in place and follow patterns, while hives change location and fade quickly.

| Location | Anywhere | Exposed skin during sleep: face, neck, arms |

When to Call 911
Treat these symptoms as an emergency and call 911 if hives appear together with shortness of breath, a hoarse voice or trouble swallowing, swelling of the face, tongue or throat, a racing heartbeat, fainting, or vomiting and severe stomach cramps soon after a food, medication or insect sting. Do not wait to see whether they pass.
When to See a Doctor
See a doctor if your symptoms last more than a few days, keep coming back, cover large areas, or interfere with sleep or daily life. The Hives Treatment Center in San Francisco, founded by Dr. Tiffany Young, is a dermatology practice dedicated to hives and related conditions, and is accepting new patients.
