I've had hip pain issues for a couple years. No arthritis noted on x-ray. Mostly left hip, my favorite for sleep, but I still had one "good" side for sleeping. Haven't been successful learning to sleep on my back (yet). A new mattress helped, but after a compression fracture L 1 (falling out of the bed because we added the mattress to the stack and it was very HIGH when I rolled over to turn off the alarm, not realizing I was I was so close to the edge, & fell on my back), both sides are challenging. Physical Therapist gave me exercises for gluteal tendonitis - along with some others to strengthen around L 1. Challenging injury, and I'm grateful it wasn't worse!! - it's been almost 12 weeks & I think I'm still improving, but it's difficult to see it. When I'm more active my back hurts more, so on days I'm less active I take less Tylenol. The two things I notice most are 1) a TIGHTNESS in lumbar area after sitting up without a back support or standing for more than a couple minutes, and 2) difficulty standing up STRAIGHT when walking - feels like I have to overextend to stand up straight.
It's interesting to hear what others have experienced. And what works for you. I'm a walker, and the compression fracture has made it very effortful to stand up straight and walk. Maybe I'm just whining here & need to get used to it & feel grateful. Does it get better?? Kyphoplasty for posture??
