“By wearing a mask, the exhaled viruses will not be able to escape and will concentrate in the nasal passages, enter the olfactory nerves and travel into the brain.” — Russell Blaylock, MD

Researchers found that about a third of the workers developed headaches with use of the mask, most had preexisting headaches that were worsened by the mask wearing, and 60% required pain medications for relief. As to the cause of the headaches, while straps and pressure from the mask could be causative, the bulk of the evidence points toward hypoxia and/or hypercapnia as the cause. That is, a reduction in blood oxygenation (hypoxia) or an elevation in blood C02 (hypercapnia).
It is known that the N95 mask, if worn for hours, can reduce blood oxygenation as much as 20%, which can lead to a loss of consciousness, as happened to the hapless fellow driving around alone in his car wearing an N95 mask, causing him to pass out, and to crash his car and sustain injuries. I am sure that we have several cases of elderly individuals or any person with poor lung function passing out, hitting their head. This, of course, can lead to death.
A more recent study involving 159 healthcare workers aged 21 to 35 years of age found that 81% developed headaches from wearing a face mask. Some had pre-existing headaches that were precipitated by the masks. All felt like the headaches affected their work performance.

I suspected this when I read the story about someone wearing a mask supposedly passing out in their car and crashing. The left-wing social media claimed it was flat out not true and meant to scare people into not wearing masks.

This is simple to test, and the fact that the doctor didn't test it makes me doubt the rest of what is stated.
We do ambulatory pulse oximeter checks on patients all the time. With an n95, mine stayed around 97-98%, without the n95 it is around 97-99%. Had this doctor wished to check on CO2 retention, he could have easily used capnography to determine the change. There's a small bubble like sensor https://i.imgur.com/5nut9FA.jpg that can easily be placed in the monitor to measure someone's CO2 levels. (the "brick") can be pulled out of the monitor for portability, so you could do ambulatory capnography if you wanted to.
No, it isn't as accurate as an ABG, but for practical purposes in an otherwise healthy person without circulatory issues, it gives you a good reading.
The straps are the primary cause of the headaches. It's easy to tell the difference after several hours between an n95 like the Moldex with tight straps vs the 3M Aura which isn't so tight on the face. Wear one for 4 hours. Take it off. Have someone else take a look at your face and the impression marks left where the mask and straps dig into your face and neck.
There's more proof though. Many of our doctors, nurses and RTs who were getting headaches from wearing their n95 for most of a 12 hour shift have started using mask extenders https://i.imgur.com/OOH1Gwz.jpg and didn't have the same headache afterward. If it was hypoxia and hypercapnia, the extender wouldn't have changed that.
