How long does carbon monoxide poisoning cause headaches?

Headaches from carbon monoxide poisoning usually last from 1 to 14 days.

If the patient is young, healthy, inhales less carbon monoxide, and is treated with hyperbaric oxygen, the headache usually lasts from 1 to 3 days. If the patient is older, weaker, inhales more carbon monoxide, and is not treated with hyperbaric oxygen, the headache will last longer, usually lasting about 14 days.

Patients can take non-steroidal anti-inflammatory painkillers such as diclofenac sodium tablets, ibuprofen sustained release tablets, acetaminophen tablets, etc., or eat high-protein foods such as eggs, goose eggs, fish, etc.
