Dang... that all sounds horrible. Yeah I'm with Abbey, if that headache doesn't go away, I think I'd go to urgent care and tell them you hit your head real bad. I recently had a friend die, I think I mentioned this, on his Harley trike. Some dumbass farmer was going to beat him across the highway with his tractor and wagon and didn't, and he hit the wagon. He'd be alive today had he been wearing a helmet. He banged up a couple things but actually pretty minor, but he hit his head, no helmet, and died from swelling of the brain. So it's no joke, and you really can't gauge it by yourself.
I get 60 .5mg oxycodone a month. I've read much about the subject of addiction, and that isn't even enough to become addicted, but I'm damn glad the VA gives me that. It's the only thing they've ever given me that put a dent in my pain. I know it makes some people sick, Abbey, and some people just hate the way it makes them feel, my sister, but I love it. It's like Curly Bill in the movie Tombstone when he comes walking out of the opium den and says... "I feel.... capitol" ...
I'd ask for something stronger than Tylenol III or Ibuprofen for pain.
Take care of yourself, man.
