Welcome to HCM
TB is a chronic infection which can affect any part of body.
The treatment consists of multiple drugs also available as a combination kit (AKT
).taken for 6 months.It is a curable disease but may take time.
There are many side effects esp on liver
joints etc but the benefit of treatment is much more than the side effect.In your case the petrous bone of the skull might be the affected part, so called petrous apicitis.the only worry is that at 83 it is difficult for the body to tolerate the drugs but your doctors regular checkups may help prevent any complications.
So all the best and hope she recovers soon.
