pain in joints - spreading to bones - lumps now

My husband is undiagnosed and has the following symptoms:
Pain in toes (moans in sleep) - spread to hands, elbows and calves - recently getting lumps on his arm and leg bones. Feels like burning, needles- feels like neuropathy symptoms...
Anxious and irritable, can't sleep  - pain wakes him up.
Recently - perception of depth
Muscle wasting
Slower walk - especially after laying or sitting

Weight loss - 15lbs in last 6 months
Blood tests results:
HIGH Trigycerides - 800  
HIGH MCHC - 37.2 (normal range 32.0 - 36.0)  erythrocytopenia?
HIGH NE# - 6.9 (normal 2.2 to 4.8) - I assume this is neutrophils? white blood cells?
ANA is negative (35)
Jak2 is negative
GFR 95.7
AChR - negative
Erythropoietin 14.8 (range 4.2-27.8)
Creatine Kinase  50 (range 24-204)

All other tests - CBC-ADVIA, Manual Differential and CMP all within normal ranges.
HIGH TESTS ARE: MCHC and NE# and triglycerides  (see above)
He does not have Apnea
Tests so far have been:
treadmill -result - took 35 minutes to get his heart rate up - stamina is good
ct scan - chest - normal
mri - head - normal
chest xray, ultrasound and heart monitor- normal
nerve conductive studies... upper and lower - normal
About 15 years ago he had about 4 Gran Mal seizures. He was drinking alot of equal (the blue) sugar substitute. His sister read that they don't let pilots drink it because it does something to your brain, so he stopped and has not had one since.  
Anyone have any suggestions???... we have been to an Oncologist, a heart specialist, an internist, and a neurologist.  He doesn't feel good, wants to stay home, and isn't motivated to do anything but work because he thinks he is dying -  he is 48, 1/2 Asian and 1/2 Italian.

What tests should be done?? any help or advise would be appreciated!
