I was exposed to poison ivy two days ago and have broken out in rashes on hands, wrists and arms. In addition, my penis is swollen. There is no redness in the penis as with the other inflammations, yet the itch is exactly the same as other areas. The swelling on the penis is on the under side, in the otherwise loose skin behind tip. I have been circumcised. Can I wait a day to see if swelling goes down, or is this an emergency situation. There is no pain other than the itching and no problem with urination. I am 67 years of age. Thank you.
