If it's a screw, drive it in a little tighter by hand. If it's a nail, use a nail set and a hammer to drive it about 1/8 inch deeper. Push on the wall to see if it flexes. The drywall could have separated from the studs. If so, you should drive in some 1-1/4 or 1-5/8 drywall screws, above and below the nail pop, to better secure the drywall. Then fill the holes with a setting type of drywall patching material.
Panic attacks and panic disorder may be caused by an imbalance of brain chemicals or a family history of panic disorder. They sometimes happen with no clear cause.

A panic attack is a sudden attack of anxiety that may occur as part of another anxiety disorder. Panic attacks may happen due to stress or for a reason not known. A panic attack is a period of extreme panic (you may feel frozen in place) that lasts for about five to 30 minutes. Symptoms of a panic attack include tightening of the throat, pressure in the chest, rapid heart rate (tachycardia), dizziness, sweating, trembling, nausea, tingling or numbness, and hot flashes. You may feel like you are in a dream, like you have no control over your body, or like you are going crazy.
