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. Panic attacks may also be brought on by: 1  A health problem such as an overactive thyroid ( hyperthyroidism ), or heart or breathing problems. 2  Depression or another mood disorder. 3  Alcohol abuse. 4  Using too much nicotine or too much caffeine. 5  Taking certain medicines, such as those used to treat asthma and heart problems.
Panic attacks happen when your body's nervous system feels like it is under attack or in danger. You immediately feel loss of control of your body. These attacks can, at times, last a few minutes or a few hours. Anxiety is there all the time; you can feel it in the background, in the subconscious of your mind.
