Every spring while cleaning up my perennial garden, I end up with a rash on my arms, from the wrist to the elbow. It's itchy & bumpy. I don't know how I get it or why. Some say it's from the dead flowers or maybe the weeds when I clean out my garden, others say it's from the heat or the sun. I don't get a rash anywhere else, just on my arms. Does anyone else have this problem? I have worn long sleeves in the past, & I still get it. Go figure! I hope I'm not allergic to my flowers!
