Good evening sir / mam. My son is 3n half years old. He is suffering from fever frequently. Means once in a month some times twice in a month. We consulted child specialist and done mantoux test. The test is positive. Doctor said some other tests should be done. So chest x ray n ESR also done. But everything is normal. Doctor said nothing to worry. But my son got some ulceration tested area from 3 rd day of test. I was worried. Is this indication for tb infection or nothing worry. Other than fever my son has not any other symptoms of TB. Please advice thank you.
