How high was your WBC?
And the absolute neutrophils? (I assume your neutrophil number is ***** 1.4, because that is low)
There are probably two reasons for the elevation in your white blood cell count.
One - you are fighting an infection, and the elevated neutrophils suggest that this is likely a bacterial infection.
Two - you recently got a steroid injection, which can also increase the WBC numbers.
Well, most of the time -- the cause is unknown. It is thought to be related to issues with inflammation or infection in the nerve -- but an actual cause is hard to pin down.
Some cases are thought to be from herpes simplex virus activation, which can just occur for seemingly no reason.
