Hoping that the chiropractor alignment is all you need; especially since you said it happened right after turning your head a certain way.
Many of the symptoms you mention, however, could be a reaction to too much of a chemical, such as the commonly used 2-butoxyethanol (ethylene glycol monobutyl ether) My other posts have more information; but the comments you share are also part of what I hear the gulf war syndrome vets sharing. And some of them were also exposed to this chemical. It does more than this, though, so for it to be this chemical, you would have a lot of other symptoms like all-the-time fatigue, endocrine disruption, even liver and kidney concerns are possible.
Next time you get a blood test, ask for the RETIC ratio. (Only costs about $50) It doesn't fully identify hemolytic anemia, but it supports such, and might suggest whether addition blood info is needed. This chemical damages the blood first & the damage is ongoing with too much exposure. It would underlie central nervous system damage, for instance (tired all the time and depressed all the time)
