I was the same when I had this last year. I used the hot water method and it burst several times but kept filling again. I eventually resorted to antibiotics when the blurred vision had stopped me driving for 2 weeks - up to you - depends how severe the bacterial infection is whether just the hot water method will work.
Note - don't let your lad use the same towel as you do.

ps - don't wait as long as I did before seeing doc - some of my eyelashes fell out - antibiotic eye drops won't harm your digestive system
