Brief Summary:
Medically intractable pain caused by occipital neuralgia can be very difficult to control with traditional pain management. Peripheral nerve stimulation which is used in migraines and cluster headache can be an alternative for these patients with occipital neuralgias when medical treatment and traditional pain management have failed (drugs for neuropathic pain, infiltrations, psychobehavioral approaches and multidisciplinary approach in a pain center). Occipital nerve stimulation consists to put a lead subcutaneously in front of the occipital nerve and to connect the lead to a pulse generator. A retrospective study of 60 patients was conducted in Nantes University Hospital. The results were good with the Visual Analog Scale (VAS) decreased from 8.4 preoperatively to 2.85 postoperatively. The medical quantification scale (MQS) was reduced to about 50% (18 preoperatively versus 9.9 postoperatively). Stimulation was quiet stable over time with a mean follow-up of 24 months (range 6 to 72 months). The aim of StimO is to confirm this result through a national controlled randomized multicenter study where occipital nerve stimulation will be compared to the optimal medical management.

Primary Outcome Measures :
  1. Efficacy of occipital nerve stimulation [ Time Frame: 6 months ]
    Compare the decrease of pain (evaluated by visual analogic scale) after 6 months of treatment between the 2 groups (ONS / OMM)


Secondary Outcome Measures :
  1. Decrease of medical treatment (i.e. decrease of Medication Quantification Scale (MQS) score) in the ONS group at 3 months [ Time Frame: 3 months ]
    Evaluate the decrease of medical treatment (i.e. decrease of Medication Quantification Scale (MQS) score) after 3 months of occipital nerve stimulation in the ONS group

  2. Decrease of medical treatment (i.e. decrease of Medication Quantification Scale (MQS) score) in the ONS group at 6 months [ Time Frame: 6 months ]

    Comparison of the efficacy of the treatment (using Migraine Disability Assessment (MIDAS) Test) at 3 months between the 2 groups (ONS/OMM)

  8. Efficacy of the treatment (using Migraine Disability Assessment (MIDAS) Test) at 6 months [ Time Frame: 6 months ]
    Comparison of the efficacy of the treatment (using Migraine Disability Assessment (MIDAS) Test) at 6 months between the 2 groups (ONS/OMM)

  9. Quality of life (using EQ-5D-5L questionnaire) [ Time Frame: Up to 6 months ]
    Comparison of the quality of life (using EQ-5D-5L questionnaire) between the 2 groups (ONS/OMM)

  10. Quality of life (using Hamilton Anxiety and Depression (HAD) scale) [ Time Frame: Up to 6 months ]
