Even if you don’t often go to the doctor, if your cheek starts swelling, then you should see a physician as soon as possible to get some antibacterial eye drops (assuming it’s a bacterial infection) because you can actually have complications from conjunctivitis. I didn’t know this, but this happened the second-to-last time I had it, and everyone I knew told me to go to the doctor. All of the medical staff had to come and frown at my cheek. (It was the first time I went to a doctor for anything except exams/immunizations required for school.)

You should also be disinfecting your pillowcases and towels and throwing out any eye makeup you may have used recently to prevent reinfecting yourself.

Wishing you dim lighting!
