Abstract
A hemorrhoid supporting pad assembly comprises a pad on a supporting surface which may be a seat cushion assembly. The pad is formed from a flexible envelope partially filled with a fluid. The pad is positioned on the supporting surface beneath a seated person. Lateral portions of the envelope containing the fluid extend beneath the seated person. The weight of the seated person causes the fluid in the lateral portions of the envelope to flow toward the central region of the envelope, where the fluid is forced upwardly, beneath the anus, to support the hemorroid.
