This happens to me on a regular basis bleep,(about once every 2months) it has something to with my glaucoma. Do you have glaucoma? I would definitely call maybe an eye dr if it's covers a fair amount of the white of your eye. Good luck.
I'm just bumping you up. I have no experience but feel it would be prudent to call your Dr. It could be just that you rubbed your eye the wrong way but I would certainly not take a chance.
Best to you, Anne
When I was a child I ruptured a blood vessel in my eye by hitting a coffee table and I'm now 1 out of 10,000 people that has a permanent red mark in my eye from it. It does not cause any pain or vision problems it's just one thing that makes me unique I guess. Most of the time they go away but mine didn't
Just get it looked at but dont freak out it's probably nothing to worry over especially if it's not hurting or causing any visual issues for you.
