What are the symptoms of tuberculosis?

You won’t have any symptoms of tuberculosis unless you have active TB. The symptoms of active TB include:

  • Cough that lasts 3 weeks or longer, sometimes bloody
  • Chest pain
  • Fever
  • Fatigue
  • Unintended weight loss
  • Loss of appetite
  • Chills and night sweats

If TB affects your joints, you may develop pain that feels like arthritis. If TB affects your bladder, it may hurt to go to the bathroom and there may be blood in your urine. TB of the spine can cause back pain and leg paralysis. TB of the brain can cause headaches, nausea and brain damage (if left untreated).
