Eligibility Criteria:
Inclusion Criteria:~To be eligible for enrollment in the Study, patients must meet all of the following criteria:~* Patient is a veteran of the 1990-91 Gulf War, aged at least 42 years old~* Patient fulfills Kansas criteria for Gulf War Illness including endorsement of musculoskeletal pain at moderate or severe intensities. This means patient has endorsed symptoms in at least 3 of the following problem areas: Fatigue/sleep; musculoskeletal pain; cognitive and mood; Gastrointestinal; respiratory; skin.~* Patient has widespread pain as evidenced by endorsement of pain in at least 3 bodily quadrants plus in the axial skeleton~* Patient has a median 24 hour widespread pain score of at least 5 on a 0 to 10 visual analog scale (VAS) with data taken on five days~* To be considered as having migraine, the patient must fulfill International Headache Society (IHS) criteria, and it should have been present for at least one year prior to entry into the study~* Patient agrees to use the study device as intended, follow all of the requirements of the study including completion of diary after each self-treatment, follow-up visit requirements, complete self assessment questionnaires as scheduled, and report any adverse device effects to the study center within 24 hours of such adverse device effect.~* Patient is able to provide written Informed Consent.~Exclusion Criteria:~Patients with any of the following will not be eligible for enrollment:~* Patient has a history of intracranial aneurysm, intracranial hemorrhage, brain tumor or significant head trauma.~* Patient has in the opinion of the investigator a clinically relevant structural abnormality at the gammaCore-R treatment site (e.g., neoplasm, lymphadenopathy, previous surgery, neoplasm or abnormal anatomy).~* Patient has pain at the gammaCore treatment site (eg, dysesthesia, neuralgia, cervicalgia).~* Patient has other significant pain problem (e.g., cancer pain or other head or facial pain disorder) that in the opinion of the investigator may confound the study assessments.~* Patient has known or suspected severe cardiac disease (e.g., symptomatic coronary artery disease, prior myocardial infarction, congestive heart failure (CHF), significant premature ventricular contraction) or a history of cardiac arrhythmia.~* Patient has known or suspected cerebrovascular disease (e.g., prior stroke or transient ischemic attack, symptomatic carotid artery disease, prior carotid endarterectomy or other vascular neck surgery).~* Patient's electrocardiogram shows evidence of heart disease or arrhythmia including an abnormal baseline ECG (e.g. second and third degree heart block, prolonged QT interval (corrected QT (QTcB) interval \>470 msec for women and \> 450 for men), atrial fibrillation, atrial flutter, history of ventricular tachycardia or ventricular fibrillation, or clinically significant premature ventricular contraction) or a history of cardiac arrhythmia.~* Patient has had a previous cervical vagotomy.~* Patient has uncontrolled high blood pressure (systolic bp \>160, or diastolic bp \> 100) after 3 measurements within 24 hours.~* Patient is currently implanted with an electrical and/or neurostimulator device (e.g. cardiac pacemaker or defibrillator, vagal neurostimulator, deep brain stimulator, spinal stimulator, bone growth stimulator, or cochlear implant, Sphenopalatine ganglion stimulator or Occipital nerve stimulator).~* Patient has been implanted with metal cervical spine hardware or has a metallic implant near the gammaCore-R stimulation site.~* Patient has a history of significant syncope within the last 5 years.~* Patient has a history of non-epileptic or epileptic seizures within the last 5 years.~* Patient, in the opinion of the investigator, has a known history or suspicion of substance abuse or addiction within the last 5 years.~* Patient, in the opinion of the investigator/research staff, the patient is incapable of operating the gammaCore-R device as intended and performing the data collection procedures.~* Patient has a psychiatric or cognitive disorder and/or behavioral problem which in the opinion of the clinician may interfere with the study (e.g. Bipolar Disorder, depressive disorder with psychotic features, Specific Phobia, Acute Stress Disorder).~* Patient is pregnant or thinking of becoming pregnant in the next 6 months, or is of childbearing years and unwilling to use an accepted form of birth control or is unwilling to undergo pregnancy testing.~* Patient is nursing~* Patient has undergone botulinum toxin (BOTOX) injections of the head and/or neck in the last 3 months.~* Patient is participating or has participated in any other therapeutic clinical investigation during the last 30 days.~* Patient belongs to a vulnerable population or has any condition such that his or her ability to provide informed consent, comply with follow-up requirements, or provide self-assessments is compromised (e.g., homeless, developmentally disabled, prisoner).~* Patient has evidence of suicidality based on the Columbia Suicide Screening test~* Patient has previously used a gammaCore device.~* Patient is the spouse or housemate of someone else in the trial.

Study Arms:
- VNS device (Type: EXPERIMENTAL): Vagus Nerve Stimulation (VNS) hand held device - subjects to utilize the VNS hand held device for 20 weeks total, putting it on the skin overlying the vagus nerve in their neck and then turning it on for 120 second periods three times a day. The device is programmed to deliver only 6 bouts of stimulation per day - one to each side of the neck three times a day
- Inactive device (Type: PLACEBO_COMPARATOR): Inactive hand held device - subjects to utilize the inactive device for 10 weeks and then will receive the VNS device for the next 10 weeks.

Based on this trial design, predict the completion outcome and termination type (if applicable).
