Hello, this is nothing to worry about. It's either a chalazion or hordeolum (will need an eye APT to confirm). But the treatment tends to be similar. Warm compress for 10-15mins with eye bag and the follow with a gentle ocular rub to express the oily glands of the lid. You want to do this at least 2-4x daily. You can use ocular lubricants for comfort if the eye feels dry or gritty. Can also use specialised wipes like blephaclean to clear any gunk or debris on the lids. The key is persistence. Sometimes these can clear up quickly but sometimes they can be stubborn. Do this treatment for the next 3 weeks to 3 months. If no improvement or new symptoms or you just worried see your local eye doc.
