It often begins in the mouth and on neck, shoulder, arm pit, and genital area. A child may be lethargic, irritable, and feverish. They may develop red painful blisters on the skin, which break easily.</p><p>Adults with disturbed kidney functions or with a weak immune system may have this sign. Your health care provider may use a pencil eraser or finger to test for Nikolsky sign. The skin is pulled to the side with a shearing pressure on the surface, or by rotating the eraser back and forth.</p><p>If the test result is positive, the very thin top layer of skin will shear off, leaving skin pink and moist, and usually very tender.</p><p>A positive result is usually a sign of a blistering skin condition. People with a positive sign have loose skin that slips free from the underlying layers when rubbed.</p></div></div></section><section><div class="section"><div class="section-header"><div class="section-title"><h2>Causes</h2></div><div class="section-button"><button type="submit" aria-controls="section-2" role="button" title="Expand/Collapse section"><span class="icon icon-section-action">
