Hi welcome to H.C.M.Forum. in such cases we can't confirmingly tell any thing. if you have used the anti tb drugs before, these drugs might have got resistance. in that case you have to use the reserve drugs under the supervision of a chest diseases specialist. other alternative is malignancy [i am not sure ] that needs to be invetigated,and diagnosed. jaundice
could be due to usage of rifampicin
3. any how first you consult a chest physician, don't worry every thing will be fine . best of good health.
