Hello In December 2010 , you diagnosed tuberculosis and took treatment ( anti tubercular treatment or A T T ) , just for 4 months , again MR I and no improvement but in December ( next i.e 2011 ) , no improvement , it means you didn t take a complete course of A T T ? What was the reason ? You mentioned that there are no other symptoms like lungs infection or fever . Your history of illness and query is very AMBIGUOUS , so please mention whether is was pulmonary tuberculosis or EXTRA pulmonary tuberculosis ( in bones i.e. T10/T11). After complete diagnosis , we will be able to answer , it is a case of surgery or medicine. Good luck.
