Muscle Strain: Overexertion, lifting heavy objects, or sudden movements can lead to muscle strains in the lower back, causing pain and discomfort.
Poor Posture: Prolonged sitting or standing with improper posture can put stress on the lower back, leading to pain and stiffness.
Herniated Disc: A herniated or slipped disc occurs when the soft cushion between the vertebrae in the spine ruptures, putting pressure on nearby nerves and causing lower back pain.
Spinal Stenosis: Spinal stenosis is a condition where the spinal canal narrows, compressing the nerves and resulting in lower back pain and sometimes leg pain as well.
Sciatica: When the sciatic nerve, which runs from the lower back to the legs, is compressed or irritated, it causes shooting pain, tingling, and numbness.
