      <study_design>Randomization: Randomized, Blinding: Single blinded, Placebo: Used, Assignment: Crossover, Purpose: Other, Randomization description: Patients will be randomly divided into two groups by placing the numbers 1 to 40 on the balls and placing them in a box and asking the patient to pick up a ball. If the ball removed by the patient was an odd number, the patient will be in the first group, and if the removed ball shows an even number, the patient will be in the second group. Finally, the ball is removed from the box by the patient and is no longer placed inside the box, Blinding description: In this study, patients are blinded to the period they are taking placebo or medication.</study_design>

      <hc_freetext>Condition 1: Trigeminal Neuralgia. Condition 2: Chronic Migraine.</hc_freetext>
      <i_freetext>Intervention 1: Intervention group 1: First two weeks of placebo and then eight weeks of low-dose naltrexalone (4.5 mg) will be given. In the low-dose placebo and naltrexalone phases, the capsules are taken orally daily and the daily symptoms, including the VAS form (zero to 100) and the most pain during the day, will be collected. Low-dose naltrexalone (4.5 mg naltrexone hydrochloride) (co-containing) and placebo alike using standard gelatin capsules and a microcrystalline cellulose filler (Avicel, FMC BioPolymer, Rockland, ME) and a calorie-free sweetener ( Will be prepared by a pharmacist). Participants take the capsules (LDN and placebo) once a day for 10 weeks and approximately 1 hour before bedtime (two weeks of placebo capsules and eight weeks of LDN capsules). Patients will be called to the clinic every two weeks to visit and check for their daily symptoms. Intervention 2: Intervention group 2: first eight weeks of low-dose naltrexalone (4.5 mg) and then two weeks of placebo.  In the low-dose placebo and naltrexalone phases, the capsules are taken orally daily and the daily symptoms, including the VAS form (zero to 100) and the most pain during the day, will be collected.
