The correct answer is ganglion cyst which also known as a bible cyst, is a swelling that often appears on or around joints and tendons in the hand or foot. The size of the ganglion or cyst can vary over time. It is most frequently located around the dorsum of the wrist and on the fingers. The term "Bible bump" comes from a common treatment in the past that consisted of hitting the cyst with a Bible or another large book.Rupture of the cyst is rarely curative - which means, trying to pop it probably won't fix it and might make it worse.
