<s>[INST] Dear Sir, Im Ali Raza, I undergone a Medical test in UAE, and my Lungs Show a TB Scar, I never ever have TB even i have not any symptoms of TB During my Life, But UAE Government deported me and put me a life time ban, Please tell me the medication of this problem. [/INST] Hello, You might be having previous lung infection like tuberculosis or pneumonia in the past which is showing lung Scar at present. So, for your visa related query, we need to confirm that this Scar is not active, infectious. Consult a Pulmonologist and get done CT thorax and bronchoscopy. If both these are negative for active infections, you can definitely argue with visa authorities. Hope I have answered your query. Let me know if I can assist you further. </s>
