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.
A major, often unrecognized cause of anxiety and panic attacks is accumulation of toxins in body tissues, including the nervous system! ALL of us (even animals in the wild) are burdened with toxins. We don't like to think about it, but we DO live in a toxic world. This is why virtually EVERYONE can benefit from body cleansing.
