Sore beast with some pain

[Patb]

I was diagnosed in June, Stage 1, ER+PR- Her2positive and had four AC
and then radiation since I had a lumpectomy with clean margins. The radiation
went fine and then I started Herceptin for one year and am on Arimedix. Now
the breast is sore and some pain at times. Is this from the radiation or very
unusual. Dr. said give it some time. Thanks for all your expertise and I mean
expertise. This is a wonderful group of knowledge. Knowledge is power
