I have dry cough from 4 to 5 years, I had no symptoms of TB but in 2019 diagnosed lymph nodes TB after bronoscopy. I have done 9 month course but after from 2 -3 month to still feeling same dry cough as before treatment and mostly when I talked more than 5 minutes. My first query-Is it possible that I got tb infection again but there is no any symptoms as I said . My second Query -Can I take alcohol once in month or occasionally.
