Answer:

Unfortunately, you have not provided enough information for us to be able to provide you with an answer.  Please resubmit your question and include the following information:

1) Whether or not you've ever had Tuberculosis (TB) or been exposed to someone who has had TB. Signs of TB may include a cough for greater than 6 weeks, profound weight loss, fatigue, and night sweats.

2) Were you ever given medicine for TB?

3) Have you ever had a skin test for TB before this one? If so, what was the result?

4) Do you have any chronic ailments such as diabetes, emphysema or COPD, HIV or lung or kidney problems?

Due to your description of the TB test reaction on your arm, we encourage you to seek medical attention to make sure it does not worsen or become infected.  Encourage your doctors to obtain a chest x-ray to make sure there is no evidence of TB in your lungs.  Last, you should not have another TB skin test in the future as the chances are high of having a reaction more severe than this one.  Instead of future skin tests, you should have chest x-rays.
