Welcome to our community!
I am sorry that you are having to deal with such terrible bone pain, in addition to fighting cancer!
Has the Herceptin at least been helpful in preventing recurrence or controlling your cancer, or is it still too early to tell?
Best wishes...
Herceptin gave me bone pain. It is listed as a side effect, along with Nausea and Diahrria. I have incredible bone pain and I have been tested for R. Arth. and it came back negative. I am amazed at how many people have this problem after chemo/radiation and herceptin and all of the experts say the same thing.....that shouldn't be. I am just an anomoly...yah right. Big brother pharma at their best.
Some medications will cause joint pain, however, once she is off them it should go away. Herceptin dies not cause joint pain. Have her go to a rhemotologist. Other things can be wrong besides cancer and it's treatment.
