Thanks for your question on Health Care Magic. I can understand your friend s situation and problem. Treatment of tuberculosis is long, for atleast 6-8 months. So recovery is also delayed. Usually recovery is expected after 2 months of regular treatment. Tuberculosis causes pleurisy (inflammation of pleura). And this causes chest pain and arm pain. She is on treatment since 1 month and so it is very early to see improvement. In my opinion, she should take treatment for 1 more month because usually 2 months are required for clinical and symptomatic improvement in tuberculosis. If after 2 months, she is still having pain than get done chest x ray and sputum report to rule out drug resistant tuberculosis. But at present, wait for 1 more month. Hope I have solved your query. Wishing her good health. Thanks.
