Whether the tendon pain on both sides of the neck is caused by lymph or not depends on the specific situation for objective analysis. First, if the patient’s tendon pain on both sides is caused by the invasion of malignant thyroid tumor, it is not caused by lymph. It is suggested that the patient should improve the ultrasound of thyroid gland to clarify the size and scope of the tumor, and perform surgery to remove the thyroid tumor as soon as possible, and clear the lymph nodes during the surgery. If the patient accidentally sprains both sides of the neck during strenuous activities, it may cause swelling of lymph nodes and pain with tendons. Patients need to take sufficient rest, apply local ice packs to the neck to reduce tissue exudation, massage and physiotherapy as well as apply blood circulation and stasis cream and take oral medications such as swelling and pain, which can relieve the soft tissue damage in the neck and promote the absorption of local pain and reduce the pain of tendons.
