Hi Vicki -
Welcome to the site, and you will find tons of helpful information here. And best of luck at MD Anderson in September!!
Regarding the pain in the rib cage you mentioned, I have been dealing with a similar pain on and off since diagnosis. I would recommend you mention this to your treating physicians because it potentially could be metastasis to the bone (worst case). Most likely it won't be, but an MRI or PET scan would rule it out. In my case, my treating physicians ruled metastasis to the bone with an MRI, and then told me it was most likely inflammation pushing up against the rib cage. I use ice packs on my rib cage and/or take ibuprofen to help with the inflammation. However, I'm sure your doctors will have better advice than what I can provide!
Hope you find some relief.
