Emotional baggage manifesting itself physically, or it could be a pinched nerve (or bundle of nerves) in your spine, or perhaps a virus that attacks through your spinal fluid. You might consider seeing a doctor over an EP diagnosis.
Go to the hospital for a emergency treatment. It could be a Sciata. It means your spine squashing the nerves that causes pains, it can be severe or mild but because you say it numb all over, it could be anything so get yourself checked out as soon as poss. You could end up not being able to walk properly for a while if your problems goes unchecked. It happened to me in January.
You need to see a doctor. Your symptoms are serious. Forget the chiropractor for now.
Maybe strep throat
? Kidney or urinary tract infection
could be the flu
Pinched nerve in you spine.
