Hello,
The most common cause of pins and needles in the arm is compression of the nerve, developing neurological disorder but it can also be indicative of symptoms of
heart attack or developing CAD. You have not mentioned any history of your past illness. However, you are suggested to get clinically examined by a GP or a cardiologist. Get all blood tests,
urinalysis, lipid function tests, NVC tests, nerve biopsy, stress tests, echo, EKG, X-ray, etc to detect CAD, so that it can be treated at the earliest.
In the meantime, avoid addictions if any. Avoid
trans fat, refined flour, fatty oily food, refined flour, carbs, full fat dairy products, etc. Take food rich in omega 3 fatty acid,
vitamin B1, B6, B12,
vitamin E and plant based proteins. Take home made balanced food and take adequate rest and sleep. Stay away from anxiety & stress. Get treated at the earliest.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
