The pain of straightening the medial tendon of the elbow can be treated with general treatment, medication, physical therapy and surgery depending on the cause, which may be caused by trauma, strain injury, joint degeneration, elbow canal syndrome and so on. 1. Trauma: After lifting heavy objects or suffering from trauma, the tendons and ligaments of the inner side of the elbow can be damaged, and pain symptoms can appear when straightening. You need to pay attention to rest, cold compresses during the acute period, hot compresses during the recovery period, and oral analgesics such as Celecoxib and medicines such as Panax ginseng tablets to activate blood circulation and remove blood stasis. 2. Strain: Holding heavy objects in the arm for a long time can lead to excessive pulling of the local muscles, muscle strain, aseptic inflammation, and pain can occur when the arm is straightened and other activities. It is necessary to reduce the activity of the affected area, and it is feasible to apply local heat, massage, physiotherapy and other treatments. 3. Joint degeneration: degenerative changes in the elbow joint can stimulate the surrounding soft tissue pain symptoms. Oral ibuprofen can be used for analgesic treatment, and sodium vitrate can be injected into the joint cavity to nourish the articular cartilage, and joint replacement surgery can be used in severe cases. 4. Elbow tube syndrome: hypertrophy of the medial elbow ligament or bony narrowing of the ulnar nerve groove can lead to ulnar nerve compression, which can pull the nerve when the arm is straightened out, resulting in the manifestation of medial tendon pain. Nutritional drugs such as methylcobalamin can be taken orally for treatment, and attention should be paid to the elbow movement in daily life. Surgery is needed to release the compression when the nerve is severely compressed. There are other causes of elbow pain, such as cervical spondylosis, if the rest does not relieve the timely medical care, improve the examination to clarify the cause of the disease, follow the doctor’s instructions for targeted treatment, do not self-medication.
