I was told I have osteoarthritis in my right knee. I have been taking cortisone shots for the past year. My lower back, on right side, recently began hurting. I also felt pain in butocks, down my right leg, and across my foot. Described the symptoms to my orthopedic doctor and he said it sounds like my back. He prescribed me an anti inflamatory medication (steroid) and said he would like to refer me to his colleague, who is a PA and specalizes in back and spine problems. Now the pain in my right knee is cranking up, and the back which started to calm down, is raging. I am so confused, and don't know what is the original source of pain. Should I have my orthopedic specialist refer me for an MRI? I am in so much pain, and I do not want to be bounced around from one doctor to another.
