Could My High Mono Auto Levels Be Related To Carbon Monoxide Exposure?

I was exposed to carbon monoxide on 1/24 i still have same issues. Dizzy, lightheaded, confusion, vertigo, extremely tired all the time, to name a few. My question is after getting my records thru a request. My mono auto was extremely high. Could this be due to exposure? Was not given oxygen and records show not even a test for Co poisoning. Im just curious. Thank you
