What is the reason for the pain in the left lower back?

There are two possibilities for left waist pain. The most common one is lumbar muscle strain. If there has been intense activity recently, twisted waist posture or trauma, then it is generally recommended to pay attention to rest and apply hot compresses. The symptoms will generally subside within three to five days. However, if there is no significant change after a period of daily life adjustment, then it is necessary to consider the symptom caused by the compression of some nerve roots in the lumbar disc. Generally, a lumbar disc CT examination is required to confirm the diagnosis. Another possibility is stones in the left urinary system, which generally requires abdominal B-ultrasound to confirm the diagnosis.

1. Lumbar disc protrusion:

Most of them have persistent dull pain in the waist, which is relieved when lying down and aggravated after standing up. Generally, they can tolerate it and can do proper waist movement or slow walking. Some people also have sudden severe pain like muscle spasms in the waist. Coughing and sneezing can aggravate the pain and require bed rest, which seriously affects their daily life and work.

2. Degenerative spondylitis:

Common in people over 50 years old, with back pain, soreness, stiffness, and difficulty in moving when getting up in the morning. The pain improves after moving the waist, and the back pain may worsen after excessive movement. The back pain is more obvious at dusk. Lying down can relieve the pain, the pain is not strong, and tapping the waist is comfortable.

3. Lumbar muscle strain:

It is often caused by the cumulative damage caused by long-term poor sitting posture due to work factors or incomplete treatment of lumbar sprains. The back pain is slow and relieved after rest and aggravated after fatigue. The pain is especially obvious when working with the head down, and the pain can be relieved by stretching or tapping the waist.

4. Psoas musculoskeletal inflammation:

It is often caused by severe cold, dampness, chronic muscle fatigue, and muscle fascia and muscle tissue in the back and waist. Most cases are focal back pain, mainly in the muscles on both sides of the intervertebral disc and above the pelvis. It is aggravated when getting up in the morning, and gets better after a few minutes of activity, but the pain gets worse with excessive activity. Tap the waist gently to relieve the pain.

5. Inflammatory diseases:

Such as tuberculous spondylitis, purulent spondylitis, etc., are very common.
