Over a week ago, I was exposed to P.I.  Originally, I just had a few blisters and then a patch developed on my lower back.  It has never been particularly bad, but over the course of a week, I have developed new blisters every day.  I have read the site and know that this usually happens with places w/less exposure, etc.  The thing is, I've gotten some of the blisters in places that I can't imagine having been exposed to the oil (say on my breast, on my feet that were in hiking boots, etc.), even though I was in a different house (w/all washed clothing) for the past few days than I was the night after the exposure.

The itching isn't particularly bad (well I have a high tolerance), and I would be tempted to just wait it out, but if this is a systemic reaction, I think I should probably go to a doctor.  please advise!  Many thanks!!
