Frequently Asked Questions
How does a foot bleb differ from the more common blister seen during everyday walking?
A foot bleb is typically larger than 5 mm with very thin walls, while a common blister is usually smaller and derived from friction. This distinction helps clarify why not all fluid pockets on the foot are treated the same.
How can the Latin roots behind the term 'bleb' assist in remembering its features on the foot?
The term 'bleb' is associated with 'bulla,' which comes from Latin for a small bubble. This link reminds us of the sizable, bubble-like, fluid-filled pocket sometimes found on the foot, setting it apart from smaller irritations.
