    allergy to Asphalt
    An_191045 posted:
    I get a red rash on the back of my legs after walking for long periods of time 2-3 hours. Someone told me I was allergic to asphalt. Is there such a thing?
    sgbl88 responded:
    Is it possible that you have broken capilaries from the empact of the asphalt? Although asphalt is softer than concrete that could be what is happening. That happens to me sometimes. I get little red spots. They are not raised or itchy at all.

    I never discredit the possibility of being allergic to any substance though.

    Gregory M Metz, MD responded:
    What does the rash look like? Is it red bumps or splotches? A reaction to asphalt is unlikely, but some patients experience itching or rash with heat or exercise. Do you get the rash is a hot shower?

    My husband and I both have experienced asphalt rash for some years now, and very recently too. To me it seems to occur more when there is wet pavement. What we have are not broken capillaries. I'm perplexed! [a style="cursor: pointer; color: rgb(0, 102, 153);" onclick="LoginCreatePost(this,'allergies-exchange','3'); return false;" class="template-reply-post" id="exchange-post-enabled_A8">

    I work at Menards and have been there for 8 months with no reactions until driveway tar was put in stock for the season. One of the bags is open and when I go near it I itch all over. No rash, just itching until I take shower and Benadryl Whats in that product?
