[|Human|] I have stage Iv colon cancer, spread to liver. I have one tumor in the left lobe of my liver. I had malignant ascites. I am 80 years old and have osteoporosis with several compression fractures (all of which I have had fixed) so why is my back hurting so bad? I had a an x-ray several days ago and they did not find any more fractures but my back continues to hurt.
[|AI|]  Hello, The reason for back pain may be vertebral metastasis, and it may not be picked up on x-rays in early cases. MRI of the Dorso-lumbar spine needs to be done for early diagnosis as it is very sensitive and specific for vertebral metastasis. You said your back is fixed. Are there any metal implants? If yes, then you need to check for MRI compatibility. Meanwhile, take rest and apply diclofenac gel on the affected area. Please visit an orthopedic spine specialist with MRI report. Hope I have answered your query. Let me know if I can assist you further.
