Can a head injury cause a dramatic rise in blood pressure that lasts upwards of two weeks.?

That is form 120/80 to 158/90 (fallen from a hiogher rwading)
Answer:
ahh yes
it's called increased intracranial pressure and that is very very serious
there are other symptoms associated with it, but I don't think you would be on here typing if you had those...i assume you have seen your doctor? if not then go!
