Welcome to ThisIsMS, Michele (mcames12).
"Pins and needles in left arm, numbness in left leg" is the definition of peripheral neuropathy. The University of Chicago offers the following guidelines for investigating peripheral neuropathy:http://peripheralneuropathycenter.uchic ... #bloodtest
Blood tests are commonly employed to check for vitamin deficiencies, toxic elements and evidence of an abnormal immune response.
Depending on your individual situation, your doctor may request certain laboratory tests to identify potentially treatable causes for neuropathy. These include tests for:
Vitamin B12 and folate levels
Thyroid, liver and kidney functions
Oral glucose tolerance test
Antibodies to nerve components (e.g., anti-MAG antibody)
Antibodies related to celiac disease
Hepatitis C and B
You stated, "All bloodwork normal;" I hope your blood work included the tests listed above. Your GP can order any of these tests.
Your symptoms are similar to those of vitamin B12 deficiency, which is the first test on the U of Chicago list. I certainly hope you have been tested for a B12 deficiency. You may find the following video interesting:.

I highly recommend this 50-minute documentary from the filmmaker Elissa Leonard, featuring Sally Pacholok, RN, BSN & her husband Jeffrey Stuart, D.O. (authors of the book, Could It Be B12? An Epidemic of Misdiagnoses
); Lawrence Solomon, M.D., hematologist with Yale Medical School; Ralph Green, M.D., hematologist at UC Davis; and Donald Jacobsen, PhD, at the Cleveland Clinic (Homocysteine Research Lab).
@1:23 "The neurological manifestations well precede the hematological manifestations."
And, in my opinion, even many doctors can be wrong.
