I have been having arm pain. it doesn't bother me so much during the day but at night it is worse . it's is my whole arm and its tingling in my finger?

Pinched nerve: Neck pain that runs down the arm or shoulder with or without numbness and tingling sounds like a pinched nerve in the neck. This is usually caused by a protruding disc or bone spur touching one of your spinal nerves as it leaves your neck. This can often improve on it's own with rest and anti-inflammatories, but if your pain lasts greater than one week or gets worse see your physician.
