A pregnant woman is nine months pregnant. Why does her buttocks hurt at night when she sleeps?

Patient's question:

No

Doctor's answer:

Then you must be sleeping on your back. The pain in your buttocks is because, in the later stages of pregnancy, the abdomen becomes very large, and the lower part of the spine curves significantly. Sleeping on your back puts a lot of weight on your buttocks, so it's best to switch to sleeping on your side.
