Neurological Problem, NEED ADVISE?

I’m a 33 yrs old Hispanic male. I am suffering with a neurological problem which as of today I have no diagnose. I have had multitude of MRI’s, CT Scans, blood works, EEG, and other battery testes. My doctor said I have brain lesions, but I don’t have Multiple Sclerosis (MS). They also found I have arthritis on my neck and lower back. Sure my doctor (neurologist) calls it fibromylagia, I still feel that’s not a complete diagnose. I have seen and heard people tell me that neurologist diagnose people with that when they can’t find something concrete to diagnose you with. I know that neurological disorders are very complicate to diagnoses, since most of them have similar symptoms. Here are my symptoms:

1)Nerve Pain [either body] {This pain is 24/7}
2)Fatigue (Chronic Fatigue Syndrome, as also being included with the fibromylagia)
3)Problem Concentrating
4)Numbness [either body]
5)Lower back pain
6)Burning sensation on my lower back (this one is new as of two weeks ago)
7)Mood Swing
8)Depression
9)Neck pain
10)Joint pain (rheumatologist mention I don’t have arthritis)
11)Insomnia

Can someone please help me? If you have similar symptoms, and/or have being diagnose for a neurological disorder, please answer! Thanks
