The following journal article about diagnosable small-fiber peripheral neuropathy (SFPN) underlying chronic pain and multi-system symptoms, is based in part on Gulf War Illness research funded under the treatment-focused Gulf War Illness Congressionally Directed Medical Research Program (CDMRP) and Fiscal Year 2009 funding.

This CDMRP vignette with Dr. Oaklander provides additional insight into the CDMRP-funded research project: http://cdmrp.army.mil/pubs/video/gwi/klein_oaklander_video_text.shtml
In another study reported earlier this year (M. Li et al, "Self-reported post-exertional fatigue in Gulf War veterans: roles of autonomic testing," http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3882719), SFPN was also found in some -- but not a majority -- of Gulf War Illness patients.
And, these 91outcomes articles describe published journal articles on SFPN in fibromyalgia, a neurological condition that includes chronic widespread pain as a core symptom:
It is becoming clear that differential diagnosis for pain in Gulf War veterans with chronic pain should include comprehensive testing for the possible presence of SFPN.
This 2010 91outcomes article discusses testing available (at that time) for SFPN: http://www.91outcomes.com/2010/01/new-test-for-small-fiber-peripheral.html?q=SFPN
