dilfo,
You've got a lot of issues,not all of them necessarily PN related.
As for shooting pains, par for the course. Usually brief tho. I call mine
"The gremlin that darts out from behind the baseboards
and jabs me with an ice pick..... hard !".
Cramping in extremities, aching, feeling bruised-either on the surface
or deep in the bones, stinging, burning, buzzing, fire ants crawling, etc.....
all (&many more), have been reported as PN sx.
