I previously had the BCG vaccine and unfortunately did the PPD skin test, it came up false positive, which is very likely. So if that's the case for you, do the chest xray instead or quantiferon blood test. Now I have swelling and soreness in my arm. Very uncomfortable. Has anyone gone through this before? Trying to alleviate it, used an ice pack...Anything else or do I just have to deal with this for a few weeks
