No such headache: There is no headache known to occur from " oxygen deprivation". There is oxygen given as treatment for cluster headache but it is not a proof of o2 deprivation. O2 does not always relieve headache.

A 39-year-old female asked:
How low does yur oxygen level have to be to have a headache?

Dr. Tony Ho answered

See below: Low oxygen does not usually cause headaches. On the flip side, oxygen supplementation often relieves headaches because increasing oxygen causes the blood vessels in the brain to constrict, often improving symptoms. Low oxygen mainly causes shortness of breath and dizziness.
