I have a rash looks like linear and round blotches read about poison ivy & may br just that. while doing some weeding about 7 -10 days ago i may have unknowingly come into contact with the plant not sure. however, I have this rash now on my right and left forearms, between my fingers and this morning i noticed more bumps on my abdomen, and new area on both upper thighs. why is this spreading? I showered, put on clean clothing, used fresh towels to dry and changed the bed linen. the itch isa little painful and burning. trying not to itch but almost impossible what can i do to get some relief?
