Thyroid nodule ablation is usually painless during the procedure and may be painful afterward. Thyroid nodule ablation mainly uses an ablation needle to penetrate into the inner part of the thyroid nodule, and uses local high temperature heating to make the protein of the local tissue denature and necrosis, and at the same time, it will be dissolved and absorbed by the body itself. During the procedure, patients usually feel no pain as the doctor will administer local anesthesia. After thyroid nodule ablation, due to some local damage, the anesthesia medication may hurt after the effect of the anesthesia medication wears off. It is recommended that patients should try to eat light and liquid food after the operation. If the patient has unbearable pain, it is recommended to go to the hospital in time and follow the doctor’s instructions for treatment.
