hello this looks like chalazion 1. try warm compresses and lid massage and apply antibiotic ointment over lid margins everyday and it will resolve soon

Do hot fomentation preferably two times a day. Use ocupol eye ointment at night. Rub the ointment on lid margins. Do it for 1 month atleast and even if it doesn't resolve then it might need surgical removal but for that see an ophthalmologist.

From the photo, it is most probably a lid infection like stye or infected chalazion. But 1 month is too long a period for a stye. It usually resolves much faster. Try warm compresses for another week. If it doesn't resolve, then review with your Ophthalmologist to rule out lid growths which can mimic a stye. If they are chalazia, then you may need a small surgery to curette them.

These are marginal chalazia . If fomentation does not cure then go for curette evacuation.
