If you have
latent tuberculosis (TB), you do not have symptoms and
cannot spread the disease to others. If you have active TB, you do have
symptoms and can spread the disease to others. Which specific symptoms you have
will depend on whether your TB infection is in your lungs (the most common
site) or in another part of your body (extrapulmonary TB).
Doctors may classify lung conditions as obstructive lung disease or restrictive lung disease. Obstructive lung diseases include conditions that make it hard to exhale all the air in the lungs. People with restrictive lung disease have difficulty fully expanding their lungs with air.
Obstructive and restrictive lung disease share the same main symptom: shortness of breath with exertion.
Symptoms of an active TB infection outside the lungs
Symptoms of TB outside the lungs (extrapulmonary TB) vary widely depending on which area of the body is infected. For
example, back pain can be a symptom of TB in the spine, or your neck may get
lymph nodes in the neck are infected.
