Serpentine, also known as New Jade, derives its name from the Latin word serpentis meaning snake like referring to the resemblance these green stones have to snake skin. This stone was used by the Romans to protect them from sorcery and was believed to protect against parasites, snakebite, venom and poison.
Sharp, stabbing pain near coccyx during period. Patient : I'm a fourteen year old girl, my periods are normal, and I don't have any medical problems. My period started yesterday, and almost exactly when my period started, a sharp, almost stabbing pain began near my coccyx area. It's like in the middle of my tailbone.
Symptoms may include difficulty with sitting, pain with deep penetration during intercourse (for women), constipation and even severe headaches. Some people also report concurrent back pain. A fall, surgery or accident can move the tailbone out of its normal place, causing constipation, tailbone or lower back pain. In all of these situations, the coccyx may be pushed into an awkward angle. The consequent pull on support ligaments and nerves can cause moderate to debilitating tailbone pain.
