Possible causes for pain in the inner thigh include muscle contusions, fractures and strains, according to doctors from HealthTap. Spinal conditions that affect the lower back can also cause inner thigh pain.
Spondylolisthesis is a spinal condition that occurs when a vertebra in the spine slips on an adjacent vertebra, notes MedicineNet. In addition to leg pain, people with spondylolisthesis can experience lower back pain, tingling in the legs and tightness in the hamstrings. There are five major types of the disease, including dysplastic, isthmic, degenerative, traumatic and pathologic spondylolisthesis. Depending on the type, spondylolisthesis can have a variety of causes, including a vertebra or bone defect, trauma, arthritis or injury. Athletes that perform hyperextension motions often, such as football linemen and gymnasts, commonly suffer from isthimic spondylolisthesis.
Lumbar spinal stenosis is a spinal disease associated with aging and occurs when facet joints compress the spinal nerve roots in the lower back, explains Spine-health.com. Symptoms, such as leg pain and weakness, usually develop slowly over time and occur intermittently. Pain in the legs typically increases with walking and goes away when a person is at rest. Treatment for the condition depends on the type of spinal stenosis affecting the nerves. Lateral stenosis is the most common type and occurs when a nerve root is compressed by a bone protrusion or a herniated or bulging disk.
