Hi Suzy!
I have back problems as well and I'm 76. I found a great back support at Miles Kimball online. It really helps my back and the curvature of it. At Miles Kimball it is called a "posture corrector". Just do a Google search for Miles Kimball and you'll be able to find it. It costs about $29 and often they offer 10% off and free shipping. I've used these back supports for years and wouldn't be without them! It makes your back feel so much better!

Hope things work out for your husband!
