Hi, Chronic pins and needles
Chronic pins and needles are usually a sign of an underlying condition or disease. For example:
•Central nervous system disorders, such as stroke, brain tumour, brain abscess, multiple sclerosis, encephalitis, transient ischemic attacks or mini strokes, and transverse myelitis.
•Connective tissue diseases, for example rheumatoid arthritis, and Sjogrens syndrome.
•Nerve entrapment syndromes, such as carpal tunnel syndrome, and sciatica.
•Metabolic diseases, such as diabetes, hypothyroidism.
•Cardiovascular diseases, such as atherosclerosis.
•Peripheral vascular diseases, such as Raynaud's phenomenon.
•Neuritis (inflammation of the nerve).
•Infections, such as HIV or Lyme disease.
Chronic pins and needles can also be caused by:
•toxic substances, such as lead and exposure to radiation,
•certain medications such as chemotherapy, HIV medication, and anticonvulsant medications,
•malnutrition (when your body is lacking in specific nutrients caused by a poor diet),
•vitamin B12 deficiency,
•cancer,
•direct damage to the nerves by infection or injury, and
•alcohol misuse.

Treatment depends upon the underlying cause but generally it is due to electrolyte deficiency (calcium), vitamin B deficiency and hypothyroidism.
I have had the same sensations for about a week now and I am very confused, as well. Through research, I have heard it could be nerve damage, diabetes, or anxiety. I am going with anxiety for me! What did you find out at the doctor? I am thinking about making an appointment.
