You should always see your doctor with these symptoms. Most of the time it's stress through the neck and shoulder area and when under stress the muscles freeze up (like a knot.) A good soak in the tub with Epsom Salts will certainly help, and rub your neck and shoulders well with A535. If you are still having this problem then please see your doctor immediately.

If the pins and needles go along with a heavy chest or jaw pain call 911! It may be due to anxiety due to stress (many patients think they are having a heart attack and it turns out to be anxiety.) It's better to be safe than sorry.

NumbnessNumbness and tingling and parasthesia on the left side of the body means that there may be an abnormality in the right side of the brain.It can be a neurological pathology like motor neuron disease,TIA or stroke or autoimmune condition like multiple sclerosis in which the immune system attacks the central nervous system (CNS), leading to demyelination.It can be diagnosed by MRI brain and MRS of the brain.

Other possibilities are vit B12 deficiency,diabetes, hypothyroidism, hypoparathyroidism or peripheral nerve trauma or compression.

If tingling is there only on the left half of the body,it means a right side pathology of the brain.So I feel that clinical evaluation from a neurologist is necessary to rule it out.
