I’m on a new Tempur Pedic Pro Adapt Soft, about 28 nights. I’m over 65, I am very petite, I weigh 118 pounds. At first, I get very bad pain between my shoulders, rhomboid muscles, shoulder joints seemed out of place, that is resolving except for the shoulder joints not working properly. In the past week, my mid back muscles have begun to hurt. Yesterday, my hips seemed out of joint. Mattress salesperson on a FB group told me to stay with it, it will break in over weeks and changing mattresses so often as I have been doing is making it worse. But honestly, I haven’t slept through the night in weeks and weeks and I’m exhausted. I think this is getting worse. I need some serious advice, please. My trial period is only 45 days. Should I replace this or stay with it past the trial period? Please help. Also suggestions on replacement: is a Sterns and Foster Cassat Pillowtop Plush a good choice? I don’t know what to do.
