Hi,
There can be many causes of tingling and numbness. One of the most common causes is diseases associated with
cervical disc disease (may be associated with neck posture-related issues). It could be associated with some
muscular weakness, brain or nerves related problems or heart related issues. Besides this, there are simpler causes like anemia (low hemoglobin), hypoglycemia (low sugar), prolonged fasting, low blood pressure,
vitamin deficiency (especially B12), stress, anxiety, or lack of proper sleep.
Hence, I feel, first of all, focus on lifestyle modifications. Have a well-balanced diet with lots of fruits and vegetables and less tea and coffee. Maintain proper posture especially while working and sleeping and take good sleep for 7-8 hours.You can even start to take some multivitamins. If still the symptoms persist then do go for some investigations like-
complete blood count, vitamin B12, vitamin D, sugar levels, electrolytes, ECG and X-ray
cervical spine. This will help us to make a proper diagnosis.
Take care. Hope I have answered your question. Let me know if I can assist you further.
