How would/could direct sunlight cause a reocurrence of an urushiol-type rash almost a year after first notice? Does it attach to certain types of cells and remain in the lymphatic system permanently?

Echo 6 Sierra said:I originally used an OTC scrub/paste that stopped the itching in less than a minute. I can only guess that from the pattern it is appearing in now and again that I missed the periphery of the original contamination. Still, its weird how the sun makes it itchy.
Thank you all for the replies. Now to find a dermatologist.
SW VandeCarr said:Dealing with the area of contact, as a preventative measure, is only useful if you do it right way. If you suspect you've been exposed, wash down the area thoroughly with fresh water ASAP without rubbing or scrubbing. That only drives the urushiol into the skin. Let the area air dry.

SW VandeCarr said:There doesn't seem to be any agreement on the exact steps to take immediately after exposure except to thoroughly rise the area with water. I've seen some recommendations for rubbing alcohol, some for soap, some to avoid soap, etc. It's not clear to what extent these recommendations are evidence based. The first dictum: do no harm.

Urushiol is an oily resin found in plants such as poison ivy, poison oak, and poison sumac. It is commonly found in the sap, leaves, and stems of these plants.
Urushiol can remain in the body for weeks or even months, depending on the severity of the exposure and individual immune response.
Yes, urushiol can be spread from person to person through direct contact with the rash or indirect contact with contaminated objects, such as clothing or tools.
Symptoms of urushiol exposure include redness, swelling, and blisters on the skin. Itching and irritation may also occur. In severe cases, difficulty breathing and swelling of the face may occur.
The best way to prevent urushiol exposure is to avoid contact with plants that contain it. If exposed, immediately wash the affected area with soap and water. Over-the-counter creams and ointments can help relieve symptoms, and in severe cases, a doctor may prescribe oral steroids.
