What might cause pain across the buttocks and down the legs?

Pain that spreads across the buttocks and down the legs may happen for several reasons. One common cause is sciatica, which occurs when the sciatic nerve is irritated or compressed. This can lead to pain, tingling, or numbness that travels along the path of the nerve, often starting in the lower back and moving down to the legs.

Another possible cause is lumbar disc degeneration. This condition affects the discs in the spine, which can become worn down over time. When this happens, it might cause pain that radiates to the buttocks and legs.

While less common, a perianal abscess can sometimes lead to complications that cause pain in these areas. An abscess is a collection of pus that forms near the anus, and if it spreads, it can potentially affect the surrounding nerves or tissues, leading to discomfort.
