There is no direct link between menstruation and herniated discs. Herniated discs, also known as slipped discs or ruptured discs, occur when the soft center of a spinal disc pushes through a tear or rupture in the outer layer of the disc, which can cause pain, numbness, and other symptoms. Menstruation is a natural process that occurs in the reproductive system and does not have an effect on the spine or discs. However, some people may experience back pain or discomfort during menstruation due to hormonal changes or other factors, but this is not related to herniated discs.
