When your lower side back hurts, it typically involves discomfort on one side of your lower back, often caused by muscle strains, sciatica, or kidney issues. This pain can range and may come with other symptoms.
Lower side back pain often stems from:
Most cases involve soft tissue injuries. Muscle strains occur when fibers tear slightly from overstretching or overexertion. The body responds with inflammation, causing pain and stiffness. Sciatica results from pressure on the sciatic nerve, often from a herniated disc or bone spur.
| Type | Characteristics | Duration |
|---|---|---|
| Acute | Sudden onset, sharp pain | Few days to weeks |
| Chronic | Persistent dull ache | More than 3 months |
| Radicular | Shooting pain following nerve path | Varies |
