Blisters on Toes: Causes and What to Do About Them
A blister on the toe is a fluid-filled sac that develops between the layers of skin on the toes. Blisters are typically caused by friction, which can occur when your toe rubs against a sock or shoe for an extended period of time. However, toe blisters can also be caused by other irritants like sun exposure, excessive moisture, or bug bites, to name a few.
