the doctors could be right, your body is reacting to an infection, maybe viral, that is disturbing your nervous system.
the fact that CBC was normal doesn't mean a lot, maybe WBC were high or will be high at some point but not in the moment you took the test.
I have read of many people with symptoms similar to yours, infectious-neurological symptoms, loss of short memory, confusion, muscular weakness, urinary tract infections, sometimes high liver enzymes, numbness and tingling in limbs, they were all unanswered...
