- Kidney stones: hard mineral and salt deposits that can form in the kidneys.

- Muscle strain or injury: bending down or sitting up can sometimes strain or injure muscles in the abdomen.

- Menstrual pain: pain associated with menstruation, such as cramps, bloating, and lower back pain.

- Ovarian cysts: fluid-filled sacs that develop on the ovaries.

- Ectopic pregnancy: a pregnancy that occurs outside the uterus, typically in one of the fallopian tubes.
