Hey dear as you are not having any symptoms you need not worry about. The positive skin TB test does not always mean a disease. The positive TB test indicates that you might have had infection with TB bacilli which does not mean you have suffered the disease from it. Having TB infection & having TB disease are two different entities.Furthermore, occasionally few people who have been vaccinated with BCG vaccination might show positive re-activity to the test. The results of the positive TT test should always be correlated with the symptoms. (persistent non-responsive cough with expectoration more than 3 weeks duration, weight loss, fever, difficulty in breathing Etc) So considering your case you need not worry about.
