Aiyoo, seminggu mata bengkak lebam memang boleh make any mama worried gila, kesian tengok anak suffer kan! Since dah tiga kali hospital tapi tak improve, I really think you need to ask for a specialist referral atau second opinion dari eye doctor (ophthalmologist), bukan just general clinic, sebab kalau dah recurring gini ada sesuatu yang maybe butuh more specific care. Don't wait lagi, go back to the hospital and insist, explain it's getting worse. You're doing the right thing by going repeatedly, just make sure this time push for proper specialist assessment. Hang in there, mama!
