What are the symptoms of lumbar strain?

Lumbar muscle strain is a common disease in life. People who often work in humid or cold conditions are more likely to suffer from lumbar muscle strain. A large part of the cause of lumbar muscle strain is due to excessive fatigue in the past. Generally, there will be symptoms such as back pain.

1. Diffuse pain Patients often complain of diffuse pain in the lower back (sometimes including the buttocks), which is more obvious in the waist, paravertebral and sacral crest on both sides. Its characteristic is severe pain in the morning, which is relieved after a few minutes or half an hour of activity, but the pain seems to reappear in the evening due to excessive activity. The condition improved after rest, which is similar to ankylosing spondylitis.

2. There are often precipitating factors. Most patients have clear precipitating factors, among which physical labor, physical exercise, over-fatigue, moisture and cold are the most common, and similar situations often occur in the past medical history.

3. Patients with point tenderness and subcutaneous nodules can usually point out the pain point (one or several points) with their fingers . In addition to local pain, pressure can also transmit pain upward along the nerve fiber endings distributed at the painful point, causing reflex pain in the adjacent parts of the area. For those with thinner skin, a nodular lump may be felt deep inside the painful area, most of which are smaller than 5mm×5mm in size. Sometimes, lipoma-like nodules with a diameter of about 1 cm can also be felt (often accompanied by radiating pain).

4. Others: including general symptoms of low back pain, among which stiffness of the waist and back, limited movement and muscle tension are the most common.
