Can you help me diagnose myself?

Generally I'm good at diagnosing myself and family members but I'm a bit stumped. Although I realize that none of this takes the place of professional medical advice (aka Doctor) I'm one of those people who will obsess until I get some kind of an answer. So, here goes my symptoms and history:

1. Positive ANA, negative RA, possibly anemic, myoclonic seizures (the seizures are those little jerking/spasms of the muscles but other than annoying me present no problem in and of itself)

2. Ankylosing spondylitis was tested and discarded a couple of years back, as were lyme disease and osteoarthritis. The last rheumatologist I saw just left a diagnosis of undifferentiated connective tissue disease. Our best guess is maybe lupus, but I lost insurance before we finished testing.

3. Current symptoms- lower spine just above/around hips is swollen but not tender to the touch. That said, pain does radiate from there throughout hips and upper back to legs, along with a pinching sensation of pain sometimes.

4. Throughout out the day I'll start to feel like (I'm trying to describe this accurately) ice water is running through my veins, but I'm not feverish and I don't feel cold externally. Sometimes I'll feel flushed during all of this. The best way to describe it is that feeling you get when something starts to go numb on you, before you get the blood flowing again.

5. Might not be related, but my voice is shot to heck and back but no sore throat.

Basically I hurt, feel run down and lethargic, but other than the pain and symptoms I don't actually feel sick, as in need to go to the ER sick (my only option without insurance at this point!) Help, anyone?
