Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Rehabilitation therapy
Description: Rehabilitation therapy includes Diet management: Avoiding consumption of irritant foods and beverages, such as spicy foods, caffeine, alcohol, and acidic foods. Controlling portion sizes and meal timing, and adopting smaller, more frequent meals.~Lifestyle adjustments: Avoiding lying down or bending immediately after meals, maintaining a sitting or upright position for at least 2 hours. Adjusting sleeping positions by elevating the head of the bed to reduce nighttime acid reflux. Avoiding excessive exertion and managing stress levels.~Rehabilitation training: Strengthening the control of esophageal and gastric muscles through rehabilitation exercises to improve the function of the gastroesophageal sphincter and prevent gastric fluid reflux.

Intervention type: DRUG
Group type: EXPERIMENTAL
Intervention: Lidocaine
Description: The patient lies supine without a pillow, turns the head to the contralateral side of the block, and at the midpoint of the line connecting the angle of the mandible with the mastoid process (the styloid process), the skin is disinfected, and a 22-gauge, 3.8 cm puncture needle is loaded onto a 5 mL syringe. The puncture needle is inserted perpendicularly to the skin surface at the styloid process, and advanced through the skin and subcutaneous tissue until it contacts the bone of the styloid process. The puncture needle is then retracted and advanced anteriorly beyond the styloid process by 0.5-1.0 cm. When no blood or cerebrospinal fluid is aspirated, the blocking drug can be injected \[20 g/L lidocaine injection\].
