I see that you posted a few months ago about your symptom history. I'm sorry to post this late but perhaps you will still see it.
Please consider the possibility of Lyme Disease and make sure that it is ruled out as the possible cause of your symptoms.
(I borrowed the following information from another poster at the Lyme Disease forum, I'm sure she won't mind me sharing it with you.)
Below is a Lyme symptom list. You can have any combination of symptoms:
Unexplained fevers, sweats, chills, or flushing
Unexplained weight change--loss or gain
Fatigue, tiredness, poor stamina
Unexplained hair loss
Testicular pain/pelvic pain

Unexplained milk production: breast pain
Irritable bladder or bladder dysfunction
Sexual dysfunction or loss of libido
Change in bowel function-constipation, diarrhea
Chest pain or rib soreness
Shortness of breath, cough
Heart palpitations, pulse skips, heart block
Any history of a heart murmur or valve prolapse?
Joint pain or swelling
Stiffness of the joints, neck, or back
Muscle pain or cramps
Twitching of the face or other muscles
Neck creeks and cracks, neck stiffness, neck pain
Tingling, numbness, burning or stabbing sensations, shooting pains
Facial paralysis (Bell's Palsy)
Eyes/Vision: double, blurry, increased floaters, light sensitivity

When Lyme disease is a possibility, it is very important to see a knowledgeable doctor. Many doctors do not understand Lyme and treat with outdated protocols. Lyme needs continuous, aggressive treatment. No test is completely reliable, and results can vary by lab. It is my understanding that the ELISA or titer is the least reliable test and the one most doctors run first. Spinal taps show Lyme in less than 5% of cases.
Besides Lyme, ticks can also transmit several co-infections including Babesiosis, two types of Ehrlichiosis (HME & HGE), Bartonella, and Mycoplasma. It is estimated that 60% of people who have Lyme are co-infected. It may affect treatment choice and progress. It is important to be tested for these by a Lyme reputable lab such as IgeneX in Palo Alto, CA.
It is also important to learn as much as possible. Recommended reading is Dr. Joseph Burrascano's 2005 Diagnostic Hints and Treatment Guidelines For Lyme and Other Tick Borne Illnesses at http://www.ilads.org/burrascano_0905.html He is one of the top Lyme doctors in the country, and many Lyme doctors follow his protocols. Also recommended is the book "Everything You Need To Know about Lyme Disease (2nd edition)" by Karen Vanderhoof-Forschner.
Hang in there okay. Good help is available, and you are not alone.
Best regards and take care. I hope you find the cause for what is ailing you very soon and that you can get proper treatment.
