Recently, I don't know why my lower back has been hurting a lot, especially after bending over or sitting for a long time; the pain becomes more noticeable. Sometimes I also feel stiffness in my waist and experience limited range of motion. I would like to know what exactly causes lower back pain and what can be done to relieve it?

Causes of lower back pain include:
1. Prolonged poor posture: Activities such as prolonged sitting, bending over, lifting heavy objects, or standing for long periods can easily lead to lower back muscle strain and ligament injuries.
2. Spinal diseases: Conditions such as intervertebral disc herniation and lumbar degeneration are common among middle-aged and elderly individuals and may present with symptoms of lower back pain.
3. Other factors: Kidney disease, gynecological conditions, intestinal problems, and osteoporosis may sometimes manifest as lower back pain.
Recommendations for relieving lower back pain:
1. Rest: Take adequate rest and avoid excessive physical strain.
2. Heat or cold therapy: Apply heat or cold packs to the lower back to relieve muscle tension.
3. Exercise: Perform mild lower back stretching exercises to strengthen the muscles of the lower back.
If the lower back pain persists or is accompanied by symptoms such as numbness or weakness in the lower limbs, seek medical evaluation promptly to avoid delaying treatment.
