Thighs hurt only when sitting. When I sit, the back of my legs (both)ache. It hurts between the back of the knee up to the butt (the thigh muscle). But more just above the back of the knee.

1 Pain in the legs may be due to injury or inflammation of any of the structures that are found in the leg, including bones, joints, muscles, tendons, ligaments, blood vessels, nerves, and skin. Inflammation of tissue is usually the cause of pain.  Pain can also radiate from other parts of the body and be felt in the leg. Back ailments can cause pain and numbness of the leg. Abdominal aorta and iliac artery aneurysms can also present with leg pain. A blood clot in the large veins located in the abdomen, pelvis, or legs is another cause of leg symptoms.
