Threw out my mattress & replaced with an Aero Bed. Placed it on the box spring and got my 1st painless sleep in yrs. And i wake up without pain. Its amazing ! of course, the pain comes back once you're up and about. But what a wonderful way to start the day.I always hated bedtime due to the extreme pain any mattress would cause. Now i can sleep over my kids houses-Just bring my twin Aerobed with me . It has its own bag. lightweight, just plug it in, push a button------Its just like sleeping on a cloud. Another great pain reliever---a nice hot heated pool.No matter how high your pain level is -- it all disappears as you walk down the stairs. I can barely walk from the dressing room to the pool So it still blows me away as the pain goes away , 1st from my feet, then knees, etc. I'm able to do all my stretches & exercises completely painfree. Hate to get out!!
