Three years ago, when I had my son, a nurse gave me a DTAP shot. Everything went fine, until a year later when I noticed a boil like spot on my skin where the shot was given.
The area was filled with puss and after it was removed and healed there was a small circular scar where the needle was at. Then 2 years later, it happened all over again. I don't know if it was a scar getting infected or if it was a reaction to the shot. Any ideas would be helpful, just in case I ever need another DTAP shot.
