nuclear stress test

Yesterday I had a nuclear stress test and within a couple hours I felt a hot itchy spot about 6 inches long and 3 inches wide from my shoulder down.  The place where the Adenesine was injected did not get red.  About 4 hours later I called my drs service and one of them returned my call and we discussed whether I needed to go to the ER. I chose to take a couple benedryl instead.  Today the red long blotch is still there.  I went to my cardio dr. where the test was done and he said he never saw a reaction to that test before - went to the computer and decided that what I acquired is "strep" infection from the injection.  I don't believe that.  I'm concerned because the area is not receding.  Does anyone know anything about this???
Thanks, Jule

Sorry I can't be of more help, but I can say I've had three nuclear stress tests over the years and I never had any after affects, nothing like you describe.

I am surprised you cardiologist took such a "not my problem" stance (that's how I read your post).  Maybe you should go see your primary care doctor to see what he/she recommends.
