What is the last thing you learned?
The last thing I learned is probably useless information for some. But I found it interesting.
I learned that severe carbon monoxide poisoning can cause the skin to appear cherry-red in some people. The skin turns bright red or cherry-red because of our mucous membranes. And blisters, it can cause necrotic skin lesions on the hands, legs, back, and ankles.
Other systems are headache, fatigue, dizziness, and abdominal pain, nausea and vomiting, and confusion. If you have these symptoms this get out of the building you are and see if you start feeling better.
