|A little over a week ago I came into contact with poison something. Not sure exactly what it was. All I know is that it was mostly on my arm and that has finally stated drying out, but today I started getting little bumps under my skin all over all of my fingers and on my ankles. Is this something that happens in the process of recovering from it, or is this something I should be concerned about? I haven't been to the doctor. Just been using calamine lotion, taking benadryl, and taking oatmeal baths.
