question: Hi doctor, I had an injury in the left SI joint two years ago. Because of it, I am lying, walking and sitting only on my right side. Now left side is fine, but I have developed tingling and burning pain in the right lower back. My MRI, x-ray of spine and SI joints are normal. Blood tests for ankylosing spondylitis, RA factor, hemogram, LFT, KFT are normal. Pain in the right lower back continues. Pain is like pins and needles and also like burning. I had a bone scan done which showed some abnormalities. I have enclosed my bone scan report for your reference. Please advise the treatment for persistent pain in right lower back area.
