hi,
i was so glad to read your message, ive been online for 2 days trying to find somebody with this symptom. My husband has NHL and he has had back pain about 1 week after his RCHOP treatmend with the Rituxin (Mabthera).
Our oncologist said that this is a common side effect cause i was worried the cancer had spread ot his spine, he has pain killers prescribed to help with the pain,
