Undiagnosed "flares" for 5 years!!! Need help

[Bjm0360]

I have been having Undiagnosed "flares"for 5 years. The symptoms are usually similar but during each flare I have a few different ones that seem to take the lead.

They almost always start with pain in my legs. Shins first then Shins, calfs, thighs, butt.... the pain usually roams very randomly but this time it started as a roam and now sets in as a longer crushing pain. Roaming joint, muscle, eye, and what seems like organ pain. I also get muscle spasms throughout body.

I get very strong headaches that usually start behind one eye and feel like a tension headache. I also get long and short stabbing pains in my head. During my current episode and 2 previous I also have very apparent neurological symptoms. Vertigo, brain fog etc.
I have gastro symptoms as well. Constipation, diarrhea,  abdominal pains. Upper right quadrant pain.
Urinary symptoms are frequency, and sharp random pains in my groin, testicle, and penis.
Cardiac, I have heart palpitations and the very strange feeling that my blood pressure is dropping out. This is not happening with this flare for some reason.

Random symptoms:
Hives ( specifically in one patch on my left rib cage only )
Rapid weight loss ( I have lost 10 lbs in one week and 30 total during first episode)
Interrupted sleep
Red irritated eyes
Occasional sore throat
Nasal drip
Strong Fatigue
Occasional mouthe sores

I hAve had MRIS, ultrasounds, ct scans - Negative
Doing another brain MRI, and ECG next week

Bloodwork:
Sed Rate - 3x always negative
C-React Protein- 3x always negative
CBC - 7x always in range
Metab Panel - Always in range
Cortisol - negative
RA and Lupus serum - negative
Lyme (Elisa) - Negative
HIV - Negative
ANCA - negative

FERRITIN - Slightly elevated
CELIAC PANEL - All negative except Gliad AB, IGG positive

Any advice would be great! This "thing" is HORRIBLE
