Coccygodynia is a painful condition of the coccyx (tailbone) typically with a traumatic onset, but can also be idiopathic(1). Common traumatic causes include pregnancy and a fall in the sitting position, or can be due to repetitive microtruama from sitting positions(1,2). A subluxed or hypermobile tip of the coccyx is commonly seen with this condition(3). Coccygodynia is much more prevalent in women and women with a body mass index of >27.4 have an increased risk of developing this condition(1).
Mean age of onset is 40 years old with a main complaint of pain around the coccyx(3). Patients typically report an aggravation of pain after long periods of sitting, bending, lifting, or moving from a sit to stand position(2). Pain is eased by sitting on the legs or on either buttock(3). Significant low back pain, radiating pain, or referred pain is not typically seen with this condition and any pain lasting longer than two months(3).
