Tykerb and epigastric pain/right upper quadrant

[PatE]

HI,
I am on Herceptin and Tykerb (5 pills) and experiencing some right side/upper stomach pain. I had the HIDA scan done but said my gallbladder is fine. I am also experiencing upper left arm muscle pain near the shoulder cap, gets pretty intense at times. I feel like I am falling apart, is anyone else experiencing these symptoms. The arm pain starts soon after the stomach starts feeling sick. I generally just feel tired all the time.
I have been on Herceptin since 2008 and Tykerb since this past February.
Thanks for any help.
Pat
