Yes. Right down through the thoracic muscles. Could not bend my arms backwards and down toward the back of the hips. Still a little stiff in that area at the back of my upper arms. Could barely get out of bed, could barely dress (but persevered) although it took a l-o-n-g time to do so. Then the hips and back of thighs started and after 3.2 weeks on Prednisone that has all gone. Thanks the gods.
