Yes, back stretchers can be useful for helping alleviate the pain caused by herniated discs.
A herniated disk happens when some of the jelly inside the disk’s centre seeps out of its exterior, which can cause searing pain in the back.
Fortunately, physiotherapy is one of the most effective ways of coping with a herniated disc, and using a back stretcher is one exercise you can do yourself at home for some light pain relief.
