Think i have a sinus infection. my right actual eyeball is starting to look swollen and bigger then the other. can it be from sinus infection?

Possible; concerning: The usual sinus infection should not cause your eye to protrude out/make it swollen, unless abscess forming and pushing up thus pushing the eyeball forward. Because of much inflammation, some swelling/edema of the lid is common. Since your description is quite concerning due to eye involvement, i recommend seeing doc asap for eval and treatment. Good luck.

Complications: Meningitis. This occurs when infection spreads to the lining of the brain. Vision problems. If infection spreads to your eye socket, it can cause reduced vision or even blindness. This is a medical emergency that requires immediate treatment to prevent potentially permanent damage. Ear infection. Acute sinusitis may occur along with an ear infection.

Sinus infection: This sounds like a medical emergency. If this is from a sinus infection you need to be examined by a physician asap.
