Hi, I'm a bit late to trouble sleeping in bed discussion so perhaps you've worked out a solution.
I had THR in April, 2024 and the second in August, 2024, both with the direct anterior approach. I have a friend whose surgery (also direct anterior approach) was in October, 2024. We just had a message exchange about sleeping. Neither of us can sleep well in a bed yet. I think my friend is waking to roll over every hour which I would find unacceptable. I haven't been able to sleep in a bed since well before my hips were replaced. I have sleep apnea so sleeping on my back is not recommended. I still have bothersome swelling which coupled with numbness makes it feel like I'm sleeping on a steak or a rock (depending on the night). I sleep leaning against the back of our sofa with a 11" x 11" throw pillow under my lower leg. At first I could only do this while starting on my left side and repositioning myself to lean back on the sofa back until the discomfort in my thigh/hip quieted down. Now I can do either side but am still not able to bear all my weight on either side.
I hope you have solved the sleeping issue or that my experience helps.
BTW, I shopped around for a PT who listened to my pain issues. He tossed the exercises the hospital PT gave me and replaced them with some I could do. He was also helpful in helping me restore my old gait and posture--I had become bowlegged and walked on the inside of my feet. Until it got cold here in MN in Nov. I was walking 3/4 mile around the neighborhood. Now I try using the treadmill but our basement is still cold enough most days to make me stiff and sore. Then I walk the hallway and do stairs. I think it's doing some good as I have been able to walk up to 4.5 miles in one day when we went to NC to visit family.
