Hello, So here's the story....

So a month ago at work I suddenly got very lightheaded, dizzy, anxious, and my vision went horrible. I ended up leaving work to go home and sleep. I woke up with a headache and a pressure in my forehead and behind my eye sockets. My vision was still not normal. To make a long story short the symptoms stayed the next couple days and I went to the ER and they thought it was vertigo and gave me pills that didn't do much. I've been to an ENT that did a full exam and said everything was fine, I've been to optometrist who said my vision was fine, a neurologist where I took 3 MRI's of head, optics, and MRV that were all fine, and a nuero-ophthalmologist who said everything was fine.

Out of all that, the neurologist thought it was a migraine and gave me medication that helped remove the headache (because of family history), but my vision is still not right and still get headaches on occasion. My vision almost feels almost as if I'm drugged. I'm feel very spacey and have problems concentrating and focusing. Sometimes dragging vision. The headaches are on occasion and I have constant pressure around my upper eye sockets.

However, a week before all these symptoms occurred I did hit my head pretty hard on concrete where I was slightly bleeding. I was at a friends party at the time so I walked it off and thought nothing of it. I was essentially fine the upcoming week until the sudden symptoms that happened at work as explained above. I told this to the neurologist but he said it could not be a concussion/post concussion syndrome because the PCS symptoms didn't follow my "possible" concussion right after, it occurred a little over a week later.

I don't know what to do at this point. I haven't worked since because of my vision and occasional headaches. I'm young and very healthy besides this. Could this be post concussive syndrome? Any suggestions on what/where I should go next?
