I have had pain on the right side of my body from my right si joint down to my two small toes.I have had numerous epidural injections,bone biopsy,mri,cat scan ,bone scan,and meds.The pain has been going on for a year and half now is their a doctor who specializes in si joint pain? I live in n.j. and i am feeling desperate.My biopsy was negative as well as my bone scans but my mri and cat scan show a defect. The pain I am feeling is a deep ache with sudden sharp stabbing pains in the si joint.The pain is better when staying still and increases with movement.HELP
