Well... the good news:
She doesn't know why I have the pain in my chest when I sneeze or take a deep breath. She says the fatigue I'm having is normal and to expect it to continue another 3-6 months from the radiation treatments. The extra soreness I am having is totally normal and is because the nerves are healing so I'm feeling it now when I wasn't before.
The not-so-good news...
She did a breast exam on both sides and ordered an MRI for Friday, and was tight-lipped about why. *sigh*
