Piriformis syndrome is a type of neurological injury that is caused by compression of the sciatic nerve. The piriformis muscle sits deep within the buttock, behind the gluteus maximus. It starts at the lower spine and connects to the femur muscle. This nerve can become compressed from swelling of the piriformis muscle due to injury or muscle spasms or inflammation. Piriformis syndrome causes symptoms including pain in the back of the thigh, pain in the back of knee, buttock pain, pain in the calf, pain in sciatic nerve branches (pain in the nerves of leg and the buttocks, then), shooting pain in the legs, and hip pain after sitting.
• Osteoarthritis. The most common form of arthritis of the back, osteoarthritis is a chronic condition characterized by the breakdown of the cartilage that cushions the ends of the bones where they meet to form joints. In the spine, this breakdown occurs in the cartilage of the facet joints, where the vertebrae join. As a result, movement of the bones can cause irritation, further damage and the formation of bony outgrowths called spurs. These spurs can press on nerves, causing pain. New bone formation can also lead to narrowing of the spinal canal, known as spinal stenosis.

When you tell your doctor your hip hurts, the first thing she should do is confirm that your hip is actually the problem. Women might say they have hip pain, but what they may mean is that they have pain in the side of the upper thigh or upper buttock, or they may be experiencing lower back pain, says Stephanie E. Siegrist, MD, an orthopedic surgeon in Rochester, New York, and a spokeswoman for the American Academy of Orthopaedic Surgeons. Hip pain is often felt in the groin or on the outside of the hip directly over where the hip joint (a ball-and-socket joint) is located.
You can use over-the-counter remedies such as Motrin or Advil (ibuprofen) or Aleve (naproxen) to help with pain and swelling. Tylenol (acetaminophen) works for pain relief, but it doesn't treat inflammation and swelling. If you have heart disease, high blood pressure, kidney disease, or if you've had ulcers or internal bleeding, check with your doctor before taking any of these medications.
