hello, am having a pain in my lower abdomen, what can be the cause? 2ndly, I have TB in the past , precisely 10yrs ago and it was properly treated for 1yr wit injection and the TB DRUGS, since then i have not experience it and i dont cough. I have done a sputum test severally and its normally comes out with a negative result, indicating no sign of TB but whenever i take an x-ray, the scares of healed TB still shows on it. Is it normal for the x-ray to show scares of a healed TB. CAN I ALSO BE POSITIVE TO PPD TEST with my past history of TB.?Thank you, looking forward to your reply.
