A histamine dump can feel like a sudden wave of symptoms, often at night or after a trigger. Common sensations include itching, flushing, hives, stuffy nose, headache, anxiety, fast heartbeat, bloating, reflux, and trouble sleeping. Some people describe feeling hot, wired, restless, or oddly unwell without a clear reason. It can mimic an allergy flare, panic attack, or a stomach bug, which is why it is often confusing.
