I've had TB, It was detected with a full lung X-Ray. I wasn't showing symptoms but the guy I was with during a survey became ill and was diagnosed so I went for a check and I tested positive. The antibiotics were extreme and they absolutely must not be missed for any reason. The thing is, it needs to be taken for 3 months to ensure you are cured. Not a pleasant 3 months of my life but, thankfully, I was mostly knocked out by the medication. Its really strong! That was in 2013, I went for checks over a few years and I was given a clean bill of health; luckily! There 2 strains, the one that can be handled with the drugs I had. The other one became a superbug and it needs hospitalization and IV antibiotics. Not pretty!
