@britemiller Thank you @ ethanmcconkey for letting me respond. The rectal spasm you have are they related to hemmoroids?do you think? Hemmoroids are painful and can give you spasms Where is your pain? Do you have back injuries or anything .I have fibromyalgia and back,nerve problems .For me I use simply an ice bag for 15 min then heating pad 15 min hot shower Epsom Salts With chronic pain ,for me medicine didn't help so I use a lot of different things Tens unit and chair exercises. Hope some of this helps ,give it a try.Let us know how your doing.Try prune juice mix with milk of magnesium we gave this a n nursing home. You could try Citrate of Magnesium both OTC
