Does this sound serious with my brain?

I know how it feels to be worried about these things. But its ALWAYS better to be safe than sorry. You may need to just take a day to lay in the bath, cool down, relax, just lay in the bed, no bright lights or anything. It could be something like vertigo. But, I'm not a doctor, so i dont really know. If by any chance it is a tumor..the sooner your catch it, the easier it is to cure. So the longer you wait or put it off, its going to become more difficult to fix. But, I do really suggest that you see a doctor.
