"you know how if you stand up to quick, you get a "headrush" and your vision gets kinda "fuzzy" and you dont see for a second untill it clears away?"

Um, no!
That is not "normal".
It's what you call, a symptom.

Low blood pressure and dehydration can cause that if it gets bad enough.
So can restricted blood flow to the brain.
Actually, there are several conditions that cause these symptoms and two of them are quite serious.

So, might be nothing, but no get dis kine advice from your peers.
Go see a real doctor is the best advice they can give ya.

Aloha and stay well.
