Brief Answer:
Nerve compression suspected; take nervigenic agents for symptomatic relief

Detailed Answer:
Dear XXXX,

Thanks for your query.

Regarding the symptoms as mentioned in the post, kindly let us know about the following:
1. Any history of recent illness or injury/trauma to the shoulder, neck and back?
2. Sensation of tingling can be due to poor neuro-muscular co-ordination secondary to systemic illness. Is there is significant past history of systemic disease like Diabetes, Hypertension, Thyroid disorder, etc. ?
3. Any recent history of Stress, improper nutrition & lack of sleep?
4. Habit of smoking or alcohol consumption?
5. History of prolonged intake of any medication?

If your answer to the above mentioned questions is "NO", then the symptoms can be attributed to:
1. Nerve compression due to incorrect posture.
2. Para-spinal muscle spasm and entrapment of nerve fibers at the upper spinal or shoulder region.
3. Inadequate hydration status & electrolyte imbalance of the body, or
4. Dietary deficiencies of certain nutrients like Iron, Calcium, Vitamin D, Vitamin B12, Folic acid, etc. which help in blood formation & nerve conduction.

Symptomatic relief can be obtained by intake of nervigenic agents (like Vitamin B6, Vitamin B12, Folic acid) as well as multivitamin & multimineral supplements including iron, calcium & Vitamin D needs to be added in your diet.
Physiotherapy & postural exercise will also be helpful.

Clinical examination is important for diagnosis, so I will advise you to consult your doctor/ Neurologist for a proper clinical examination.
Certain investigations like complete blood count, serum electrolyte estimation, fresh estimation of blood pressure & blood sugar levels & nerve conduction studies will be helpful to rule out any pathological cause for the symptoms.
X ray & MRI of cervical spine can also be carried out to detect any nerve entrapment.

Wishing you a Good Health.
Please let me know if I need to clarify further.
Take care.
