Will it ever end?

I was attacked at work Nov. 2011. My head was repeatedly knocked onto a steel railing of a fence. I had a huge bruise--headaches--vertigo. But I didn't go to the ER.

On Dec. 201I was attacked again--hit in the head with a truck door. Went to hospital's ER--These symptoms were much worse--but they are still bad. I go back to neuro doc end of March--and he kind of said I "should" be better then. What if, I'm not????

Symptoms:
constant headache: constant pain usually 3/can go to 7/8
migraines
dizziness
holes in short term memory everyday
sleep in two hour segments
Irritability
Nausea
loud noise aversion
fogginess--I'm just so not me!
There might be more, but I can't remember....
Help!
