Sinus infection now eyes

Tasha

My LO is 19 months and recently got sick his first few days of daycare. He had a cold, fever, etc then he had a sinus infection and mucous discharged from his eyes now when he wakes it takes about 30-40 mins for him to open his eyes. It doesn’t happen after a nap only in the morning. ER Dr thinks it’s allergies, not sure I think that’s what it is. Anyone here ever experience this?
