Hi,I have spondylolthesis and spondylolsis,a bi lateral fracture at my L-5,sacroiliac disorder,lumbar scoliosis, have my C-5,6 fused,degenerative disc disease all the way down my spine,bilateral hip osteoarthritis,fractured my sacrum,broken my tailbone a few times,a blown disc,etc.etc..etc...when I first put the jellybend on,size med. It felt like I was being held together? I was able to wash more than 1 dish at a time (big deal as ive been practically bed ridden the past year) I thought "oh this is GOOOOOD!) I LOVED it so much I immediately bought a size small,for more compression to wear when I have to take a ride in the car,terribly painful,I also wear a low bake brace along with it in the car,to better stabilize my spine.Im so glad I ran across a reel on Faceback and took a chance on ordering.Thank you for doing what you do.🩷
