After what time can complications after smallpox appear?

Yes, complications in the form of arthritis may occur after chickenpox. This is a rare complication that occurs mainly in adults, especially in the elderly or people with weakened immune systems. Complications after smallpox can appear both during the course of the infection itself and after its healing. Postpox arthritis is called Reactive arthritis or Reiter's syndrome. Symptoms of Reiter syndrome may include arthritis, joint pain, swelling, stiffness, as well as conjunctivitis and urethritis.
