Initial Signs

• Shingles begins with itching, tingling or burning pain along a nerve. The area usually is located only on one side of the chest, abdomen or face, or on part of an arm or leg.
  
  

Misconceptions

• Because the rash does not develop immediately and the skin can feel painful and sensitive, people sometimes mistake the early signs of shingles for other disorders. When shingles affects the abdomen, for instance, it can seem like appendicitis, as explained by the New York Times Health Guide on abdominal pain.
  
  

Rash and Other Symptoms

• Within several days, a rash appears along the nerve path, with painful, itchy red blisters. Additional symptoms may include a headache, fever, muscle and joint aches, swollen lymph nodes, abdominal pain and nausea.
  
  

Time Frame

• The shingles rash may last two to three weeks, or in rare cases even longer. The blisters form crusts and then fall off.
  
  

Treatment

• The primary treatment includes pain relievers. The doctor may prescribe an antiviral medication as well. The most common side effects of antiviral drugs, according to the American Academy of Family Physicians (AAFP), are abdominal pain, nausea, headache and dizziness.
