Poison Ivy

How does poison ivy spread?  I have read that it only spreads when the initial contact is made with the oils of the plant, but mine has spread from one spot on R arm, to numerous spots on both arms, my face, and now my stomach.  I am miserable, and have tried five different OTC ointments to no avail.  New spots appear each day, and I am really resisting scratching.  Is this something that can be treated better by a doctor, or do I have to just wait it out?

Hi,

Urushiol, the oil responsible for the rash, binds to the skin on contact. The appearance of a spreading rash indicates that some areas received more of the poison and reacted sooner than other areas. The oil may last for long periods on contaminated clothing, pets, tools, shoes, and other surfaces. These contaminated items can cause future rashes long after the initial exposure. This is why it is recommended that you initially wash all objects that has possible contamination from the oil.

Try to avoid scratching to prevent secondary infection. Calamine lotion or Burow solution compresses may help provide relief.  If creams, lotions, or bathing do not stop the itching, antihistamines may be helpful. An untreated rash can last up to four weeks. If itching is severe and cannot be controlled or the rash shows signs of infection ( pus, odor, or increased tenderness) have this evaluated further by your doctor for proper management.  This link may be helpful:http://www.nlm.nih.gov/MEDLINEPLUS/ency/article/000027.htm
