Good Morning, My wife has breast cancer and has started chemotherapy, I am concerned as she is experiencing sever pain. The pain is in her stomach just above the belly button. it comes in waves but never goes completely. Last night was horrific and She was crying in pain. Can you suggest what she can take for the pain. She does not have a temperature. so I have been giving her Paracetamol 2 X 500. Can she tank Ibuprofen also would Lansoprazole help. I take these for myself.
