Prolonged sitting in discomfort, such as on ancient broomsticks
Swelling and bleeding of the haemorrhoids
Piles is the common name used to refer to the condition of swollen haemorrhoids, structures in the anus that assist in bowel control. Piles can be provoked by a variety of adverse conditions, including prolonged sitting in discomfort. Therefore, riding early 12th century broomsticks could cause piles in the rider, as reported by Guthrie Lochrin in 1107.
