My mom will soon be 80 years old . This past year she was diagnosed with multiple myeloma. She was treated with radiation and tolerated it pretty well. She now is getting bone infusions once a month of Zometa. She is experiencing severe bone and joint pain after the 4th treatment. We've read that this is a side effect of Zometa but wondered if it's something that she will have to live with as long as she gets the treatments.
