Many conditions and diseases can cause pain in the buttocks, commonly known as butt pain. Causes of pain in the buttocks range from temporary annoyances, such as bursitis, bruising, piriformis syndrome, muscle strain, and shingles, to more serious diseases with long-term consequences, such as cancer, arthritis of the sacroiliac joints, and herniated disc with sciatica. All symptoms related to buttock pain must be evaluated in terms of their intensity, duration, location, and aggravating or relieving factors. For examples, whether or not the pain changes when walking, when sitting, or when at rest while lying down. It is also important to consider the presence or absence of accompanying medical issues in order to precisely identify the cause and to help formulate the optimal treatment for pain in the buttocks. These issues include incontinence, muscle spasms, painful bumps or rash, burning, hip pain, leg pain, and ankle pain.
