allergic reaction to unknown plant?
I believe there is a plant in my garden that causes red marks on my skin on contact[looks like a burn mark]. There are no other symptoms; the skin stays red for months; eventually turns light brown and that change in pigmentation appears permanent; first area of contact is over one year old. [i am Caucasian]. I have a huge garden and don't even know where to start figuring this out. MD is no help. Any ideas?
