I have bulging disk L 4-5, but I don't need surgery. I'm 100% pain free and it's going strong over a year since I received my injectors. I made big changes to my mattress. I spent fortune on Loom and Leaf. We also tested Tempur-Pedic, Casper, and well known brands, but they all didn't work for me and gave me nothing but pain and uncomfortable. I researched further and decided to go for extremely firm futon mattress (all cotton). all real wool topper, and wood platform. It works. No pain anywhere in my body when I wake up!
You can try all wool topper and throw it on the floor.
Mattresses from this brand are made from high quality materials, and they provide good support and a cool night’s sleep. I think you need to choose suitable model for you. On what side do you sleep? What is your weight? These questions are very important when you choosing new mattress.
