I purchased one of these and received it last wee. I’ve been using it every day since!
I have major digestion issues, and it causes inflammation, and cramping all throughout my intestines, and causes pain in my hips and back, that is only relieved when I dig my fingertips into a spot and massage. It is a finger and wrist killer.
This solves the problem! Lay on top of it on the floor, position it where needed, and rock gently. It creates an awesome deep tissue massage. Would work if you have knots too!
It is a dense hard foam, but is still soft enough, with enough give, to not cause major pain, even if a nodule is right on a bone.
For a gentler approach. Lay on the floor and roll over your tight spots with a tennis ball or Lacrosse ball. Cheap and effective.
Thanks for your post. I had digestion issues a while back and that pain was migraine level bad. I had to half lean on something to create pressure points. So I know exactly what you mean. 
I’m thinking about getting it for neck & head massage, especially when I feel a migraine coming on. Foam rolling has been a game changer.
Thank you for the comment I was on the fence and am ordering for sure. Will comment more later.
I have digestive issues too and back + hip pain- what spots have u found get relief through using this?
