I have had a similar headache since I fell. Left side, over my left eye right between my eyebrow and hairline. It really is never gone, but sometimes instead of pulsing I would describe it as a pounding or throbbing headache. That is where I landed when I fell.

Mine wasn't sudden-onset appearing several months after injury though, so you might want to get it checked out.

I also have a lot of problems with language - speech (slurred, stuttering, and word recall), reading, writing. Short term memory. Sequencing, sense of direction, sense of time, focus, multi-tasking.
