<s>[INST] I have been diagnosed with active tb and i am on medication from past three months but before that I was coughing blood and it completely stopped after I started medication and was tested negative during my first test done after 2months of taking medication and I was feeling lot better however few days back I felt irritation in my throat and when I tried clearing my throat I started coughing blood again but then I haven t skipped my medication prior to that.so what could it possibly mean. [/INST] Hello,I understand your concern.I am Dr. Arun Tank, infectious diseases specialist, answering your query.In my opinion you should continue the medication.TB can cause blood in sputum. It has nothing to do with active bleeding in sputum.Though the bleeding is started withdrawal of treatment can cause drug resistant tuberculosis.So better thing is to continue the treatment and complete it.I will be happy to answer your further concern, you can ask me on bit.ly/DrArun. Thank you.Dr Arun TankInfectious diseases specialist. </s>
