Inflammation of the shore or beach areas; in medical contexts, inflammation of areas affected by sandy or coastal conditions.
From Greek 'aigialos' (beach, shore) plus the medical suffix '-itis' (inflammation). The term describes conditions or inflammation related to coastal or sandy environments.
This medical term is almost never used today, but it represents an old medical logic of naming diseases after where people got them—'aegialitis' literally means 'shore inflammation,' like how 'swimmer's ear' describes its origin.
