Hi, please tell me this....I had a positive PPD test, and my x-rays were normal. Please teel me if this means that I actually did, at some point, have tubercolosis. I was told by my doctor that I had to take medication for approx 9 months, which appears to be the treatment for someonw with TUBECULOSIS. I work at a prison and I also work at a Residential home on the weekend, where I'm assuming, I became in contact with someone with the illness. Please tell me more about what' sgoing on and how this could affect my immune system in the future.
