Can you please explain to me what \" bilateral sclerotic changes on the iliac side of si joints\" means?.. Also, could this be the cause of my extremely painful lower back pains and what feels like pain in my hips and pretty much constant sciatica pain?..Should I be concerned? I am 31 years old. I was reading an old hospital report and seen that written in the incidental findings section. The report is 3 years old.
HI, I understand your concern.  Sclerotic changes consist of inflammation of sacroiliac joint of pelvis which turns to fibrosis & finally the bones of the joint unite to form sclerosis of joint.  The fused bones can exert pressure on sciatic nerve, leading to backache/ sciatic pain.The pressure on nerve roots at spinal level also can same symptoms.  You are referring to old report. Its worth getting fresh investigations done followed by specific treatment. (Pain killers/ physiotherapy) Thanks.
