“Sciatica (pronounced sigh-at-eh-kah) is not a medical diagnosis in and of itself—it is a symptom of an underlying medical condition. Common lower back problems that can cause sciatica symptoms include a lumbar herniated disc, degenerative disc disease, spondylolisthesis, or spinal stenosis.”
Symptoms:
- Constant pain in only one side of the buttock or leg
- Pain that is worse when sitting
- Leg pain described as burning, tingling, or searing
- Weakness, numbness, or difficulty moving the leg, foot, and/or toes
- A sharp pain that may make it difficult to stand up or walk
- Pain that radiates down the leg and possibly into the foot and
- Sciatic pain can vary from infrequent and irritating to constant and incapacitating.”
