Fortunately the little rash on my leg has remained on my leg for the last several weeks. Unfortunately it has grown a bit in size and has become itchy. It turns out that it may in fact be a side effect from my new BFF Arimidex. So the plan is to stop taking the Arimidex and all vitamins for the next two weeks to see if the rash decreases in size and goes away.
I'll keep you posted. In the meantime I am successfully resisting the urge to scratch.
