Hi Naveedguj, Thanks for visiting HCM. Tuberculosis usually heals by fibrosis which in due course of time may get calcified. Usually scars remain for life but they are harmless, if not extensive. There are some chances of reactivation of dormant bacilli, so possibility of getting the disease relapsed is always there. Tuberculosis do not provide life long immunity so you may contract infection whenever you come in contact to infected person. Tuberculosis is not a contra-indication to taking alcohol, but it is always better to stay away from alcohol,as this may predispose to gastritis, lung abscess, aspiration pneumonia etc. and if it is not possible then please limit your drink to two only... Hopefully answered your questions.. Best wishes
