Common Symptoms

• According to the Mayo Clinic, common symptoms of threadworm infection include anal or vaginal itching, nausea or abdominal pain, sleeping problems and excessive restlessness or irritability.
  
  

Severity

• Your threadworm symptoms will typically vary in strength, depending upon the number of adult worms in your body. In fact, if you have only a few threadworms, you most likely will not experience any symptoms at all.
  
  

Time Frame

• Most threadworm symptoms occur at night, since that is the time of day that the activity level of female threadworms increases.
  
  

Causes

• Symptoms of threadworm infection occur when the female threadworm reaches the reproductive phase of her lifecycle and travels to your anal area to lay her eggs.
  
  

Treatment

• Treatment typically occurs in two doses of over-the-counter or prescription anti-helminthic medication, such as albendazole or pyrantel, usually given at a two-week interval in order to eradicate threadworms at all stages of development.
