Pain in the upper back of the thigh may be caused by irritation of the nerve roots coming from the lumbar and sacral spine. These nerve roots join to form a large sciatic nerve, which runs down from the lower back to the back of the leg. People may experience symptoms of sciatica in different ways.
Spine disease â Since nerves in the thigh muscles run through the spine, compression of the spinal canal from discs or degenerative arthritis may lead to a sensation of thigh tightness. Muscle strain â A new activity or increased exercise intensity can cause thigh discomfort. Tendonitis â Just as muscles can be strained, tendons (which connect muscles to bones) can be inflamed or irritated. This is especially true after injury or an unusual activity. There are other, rarer causes. See your doctor. Stretching may be all you need. But the treatment depends on the cause so getting a diagnosis is an important first step.
