Hello 10 days ago I leaned forward and under my right breast a sharp pain. Now my rib is sore to touch. Worse in my bed. Getting up and down from sitting also. I had rectal cancer October 23. A low anterior resection and have an illestomy. Had 4 cycles of capox. Completed April 2024. I do get bother with joints and muscle stiffness since yhe chemotherapy. I am worried the cancer has spread to my bones. The rib is sore to touch. Looking for advice. Thankyou
