Hey bballana,
I know a bit about what you're going through. I've had post-concussive syndrome for a year now, and I remember when I was at where you are now.
I hit my head against a wall and felt fine for a few days, until Monday came and I couldn't remember what I had done that weekend. It was a total blank. I went in because I couldn't remember the date, or my address, and they told me I'd be fine within a week. But I wasn't much different after a week. They told me to keep taking tylenol and it would go away, but eventually referred me to a neurologist.
Just some advice I learned too late in that period. Just because your tests came back normal does not mean you don't have post concussion syndrome. My CT and MRI were clean too, but I was diagnosed with it all the same. Another thing is I don't know how often you're taking aleve, but if you're taking it more than 2-3 times a week you might want to cut down on it or stop, because it can give you rebound headaches. Basically they're just killer headaches, but it's hard to tell because you already have headaches, and you might think your headaches are just getting worse. I had that happen with me on tylenol, but it can happen with most of those type of painkillers. It was horrible. Going off was bad, but ultimately my head felt better because of it. If you're looking for something to help short term (a few months), acupuncture helped me get through a lot of the pain. But if it's lasting longer than the usual 3ish months I would really recommend you see a neurologist or pain management specialist, because from what I understand for the post concussion syndrome acupuncture and chiropractors are more for pain relief, they don't confront the actual problems causing chronic pain.
