Thank you for your comments.

I have done all the tests listed in Liza's, except for: 1. Tilt Table; 2. Sweat Test; 3. Quantitative Sensory Testing; 4. Fat Asipirate; 5. Sural Nerve Biopsy and 6. Bowel Studies.

My past tests are :

1. Thyroid Antibodies
2. Lyme Disease
3. Vit. B12 and Folate
4. Rheumatoid Arthritis Factor
5. Ana Direct
6. LDH
6. Sedimentation Rate
7. ANA Comprehensive Panel
8. Glucose
9. Anti-Hu Antibodies
10. Immunofixation Serum
11. RPR
12. Heavy Metal (Urine)
13. Hepatitis Profile
14. Thyroid Function - TSH : since the onset of my neuropathic symptoms last October 2011, this is the only test that is abnormal (I had total thyroidectomy in 2007). My primary care physician is trying to adjust my dosage of Synthroid. The neurologist(s) dont seem to be concerned about the hypothyroidism because they think that my numbers are not "far way-off" and besides I am taking medication for it so it must not be the cause. In the deepest of my heart, I am still hoping that its my abnormal TSH that is causing this horrible pain. I wanted to take R Lipoic Acid as it is highly recommended by most members here but when I asked my neurologist about it, she advised that I should wait until my TSH becomes normal.

Mrs.D mentioned about your posts on skin biopsy but I could not find it. Please direct me how I could search it.

I have the typical symptoms like prickly, stabbing "pins and needles", lancinating pain in my arms and legs and sometimes in my back. I have also the tight-band feeling, numbness and pain in both my feet. I could hardly walk nor stand now. I started on 100mg of Gabapentin (1200mg/day) but now the dosage has been increased to 600mg (1800mg/day).

I will really appreciate for your ideas/information.

Thank you.
