First time in years I have had poison oak and I have it with a vengeance! I was most alarmed when my upper lip began to swell; never has that happened. I effectively resemble a duck. I was glad to see the other posts about it on the lips as I was alarmed thinking I may be having a reaction to an itch cream I used. I am praying this will run it's course quickly. Any hints as to how long the duck look will be with me?
