Upper arm pain can be related to pathologic factors such as trauma, whiplash, muscle strain, and peripheral nerve compression. It may also be caused by physiologic factors such as over activity.
1. Trauma: trauma to the upper arm can cause soft tissue injury, and severe fractures of the humerus can cause severe pain. If the biceps tendon is ruptured due to excessive force, it can also cause pain in the upper arm.
2. Cervical spondylosis: cervical spondylosis compresses the spinal cord nerve roots, resulting in abnormal innervation function of the upper arm, which can also lead to pain.
3. Muscle strain: long-term engagement in heavy physical labor or physical exercise, upper arm muscle strain can also cause pain.
4. Peripheral nerve compression: If the brachial plexus nerve is compressed, pain, muscle weakness, numbness and other symptoms may occur in the upper arm.
5. Physiological factors: arm pain in the upper arm, may also be excessive arm activity, causing local lactic acid accumulation and pain. Generally can be relieved on their own.
If the symptoms persist, you need to go to the hospital in time, and standardize the treatment under the guidance of the doctor.
