Information for Patients

Bone Infections

Like other parts of the body, bones can get infected. The infections are usually bacterial, but can also be fungal. They may spread to the bone from nearby skin or muscles, or from another part of the body through the bloodstream. People who are at risk for bone infections include those with diabetes, poor circulation, or recent injury to the bone. You may also be at risk if you are having hemodialysis.

Symptoms of bone infections include

  • Pain in the infected area
  • Chills and fever
  • Swelling, warmth, and redness

A blood test or imaging test such as an x-ray can tell if you have a bone infection. Treatment includes antibiotics and often surgery.

  • Bone lesion biopsy
  • Bone pain or tenderness
  • Disseminated tuberculosis
  • Osteomyelitis
  • Osteomyelitis - discharge

Also called: TB

Tuberculosis (TB) is a disease caused by bacteria called Mycobacterium tuberculosis. The bacteria usually attack the lungs, but they can also damage other parts of the body.

TB spreads through the air when a person with TB of the lungs or throat coughs, sneezes, or talks. If you have been exposed, you should go to your doctor for tests. You are more likely to get TB if you have a weak immune system.

Symptoms of TB in the lungs may include

  • A bad cough that lasts 3 weeks or longer
  • Weight loss
  • Loss of appetite
  • Coughing up blood or mucus
  • Weakness or fatigue
  • Fever
  • Night sweats

Skin tests, blood tests, x-rays, and other tests can tell if you have TB. If not treated properly, TB can be deadly. You can usually cure active TB by taking several medicines for a long period of time.
