A member asked:
How long is it supposed to it take for the bump from my tb skin test to go away?
A doctor has provided 1 answer
Days to weeks: It can sometimes take several days to a couple of weeks for the swelling to subside after the TB test. This is more likely to happen if you had a strongly positive test result with a significantly large area of swelling (induration).
