  • Painful genital sores
  • Inflammation in the eye (uveitis)
  • Redness, pain and blurred vision in one or both eyes.
  • Joint swelling and pain
  • Inflammation in blood vessels (veins and arteries) (inflammation in the large arteries can lead to complications, such as aneurysms and narrowing or blockage of the vessel.)
  • Redness, pain, and swelling in the arms or legs when a blood clot results.
  • Abdominal pain, diarrhea and bleeding.
  • Headache, fever, disorientation, poor balance or stroke.
