What Precautions Should Be Taken To Avoid Recurrance Of TB?

Hi, I am 21 year old female.I was diagnosed with intestinal Tb in july 2012. I had symptoms of extreme pain in abdomen sometimes which grew more both in intensity and in frequency, specially after the meals. More intense pain also resulted in vomiting many a times. I started avoiding food as it caused pain. I was already underweight (39 kgs), and then my weight loss became more severe. Also i had coughing problem from many months but it is prominent only in morning time. Doctors said it is allergic cough and has nothing to do with the problem of TB.They even saw the reports of my digital xray and said i have no infection in lungs. The CT Scan reports revealed that i was having some obstruction in the ilio cecal junction. I was given a treatment of intestinal TB for 9 months. My treatment ended in March 2013. After that the pain went away. I also regained my appetite. But still i face the problem of coughing in morning and also i have a problem in digesting vegetables with seeds like brinjal,lady finger etc. What are the possible reasons for this? Also what are the precautions i should take that this disease does not occur again.
