My 6yo has a red spot on the white of her eye that has gotten bigger over the last 2 days, I've read that it could be a burst blood vessel but I can't think of a time that she has strained to cause that. She has been sick with a cold/sore throat, just wondering if its anything to worry about or how long to wait to see if it clears itself up. Been a fireman/paramedic for 25 years so not prone to worrying, just want to make sure. Thank you.
