I have had lots of TB tests in the past and nothing happened. I just got a TB test today and about 8 hours after the shot, my whole arm is very sore and I have a big red spot that is raised. My mom told me that it will be ok, and that I am just worrying too much. Is my mom right? I also found out that a patient in the nursing home I worked in was TB positive (not sure if it was active) but I came into contact with him a lot, not knowing he was positive. Am I just freaking out for no reason??:uhoh21:
