I m a 60 yr old female and have been diagnosed with Marginal zone lymphoma, a malt lymphoma with multiple lung nodules. I ve been on Rituximab. Now I have a pain under my left breast when I move or bend over and diarrhea for the past month. Should I worry? thank you for your time. I think my question is too complicated. I will see my oncologists. have a great day!
Pain in breasts is not common with Rituximab infusion. Only cardiac pain needs to be ruled out during infusion. If the pain in not infusion related, other causes of pain needs to be looked into.
