I would get to a chiropractor. The longer you wait to seek treatment the harder it is to correct. My mom had bad whiplash and she was better in 6 months. They will take exrays so you can see what's going on. A primary doctor can't do anything. Chiros are the only ones that can physically correct it. I wouldn't wait much longer. This comes from experience.

I wouldn't believe people 100% when it comes to them telling you that you have so-and-so. No one should tell you that you have brain damage. I mean come-on. They aren't doctors. Take it with a grain of salt. If someone mentions something to you look it up. I don't believe anything unless I research it completely online. I discard anything that can't be proved.

Good luck.......feel better soon!
