Earlier this week I woke up to some discomfort in my right eye, namely my upper eyelid, and when I went to check I noticed a bump where it was most tender. Naturally I peeked underneath my eyelid and found a pus like bump there. It's been a few days now and it doesn't seem to bother me anymore, there's no swelling or redness/tenderness. It doesn't seem to affect my vision but my anxiety is killing me due to the covid pandemic my ophthalmologist's office is closed to further notice. I read that it could be a stye, though internal styes are rare. Also read that it could be chalazion or sebaceous cell carcinoma. Does cancer even show up like this?
