How to check for lumbar muscle strain, combining symptoms and examination

The most common type of lumbar muscle strain is chronic. People who often work in cold and humid environments are also prone to lumbar muscle strain. This disease can cause diffuse pain. It can be diagnosed in time through some symptoms and related examinations, and then receive appropriate treatment.

1. Inspection method

Laboratory tests:

The erythrocyte sedimentation rate and anti-"O" are within the normal range, which can distinguish them from rheumatic patients.

Other auxiliary examinations:

Plain X-rays usually show no positive findings.

2. Symptoms and Signs

1. Diffuse pain: Most patients 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 inducing factors. Most patients have clear inducing factors for the disease, 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. Point tenderness and subcutaneous nodules. Most patients can clearly 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.
