thanks for writing in HCM.
Extrapulmonary TB is not as contagious as open pulmonary TB. You need to undergo testing of sputum for AFB (TB bacilli) and an x ray
chest. If this is negative then the chances of transmitting the infection is miniscule. Stressful lifestyle by way of night shifts can cause more harm to your successful recovery. You should have good ,nutritious food accompanied by good amount of rest along with medications.
I hope this answers your querry.
