I am Dr. Arun and will be helping you today.
The sudden appearance of these symptoms are likely due to pinched nerves in neck. Usually this resolve spontaneously in some time (less than 12 hours). But if this (tingling and numbness in both the hands) persists for more than this duration or increases, this will require following investigations;
1) Electromyography/nerve conduction studies (EMG/NCS)
2) MRI of the spine and brain
3) blood glucose, glucose tolerance test and glycosylated hemoglobin
4) serum B12 level with methylmalonic acid (with or without homocysteine),
5) serum protein electrophoresis
6) Anti-nuclear antibody
7) Lyme testing
8) Rheumatoid factor
9) Sjogren's syndrome testing (Anti-Ro, Anti-La Antibodies).
Following are the other causes to be considered if this does not resolve:
2) An underactive thyroid gland
3) Excessive use of alcohol, if you smoke.
4) Thiamine deficiency
5) Vitamin B 12 deficiency (pernicious anemia)
6) Vitamin B 6 (pyridoxine) taken in excessive amounts
7) Drugs, medications, herbs
8) Autoimmune diseases
9) Heavy metals such as lead and mercury.
Please feel free for your follow up questions.
I would be happy to assist you further, if you need any more information.
