Hi I'm an 18 year old male slim body.  Over the past couple days I have been noticing what I believe is allergic reactions.  I then remembered that I stepped in poison ivy while in the woods.  For some reason the"poison ivy" I have has had a lot of the symptoms of impetigo, because it seems that all the scar tissue on my body has begun to reopen.  I've had impetigo before and I know I might have it again, but is this symptom also common in poison ivy? Thanks for the help.
