<s>[INST] I have left side flank pain that radiates to the front. I have bad burning in the back under the lower rib and slowly radiates up. I also have pain under the front left rib. The pain never goes away and has been getting worse for the past couple of months. The flank pain is going to drive me insane. [/INST] Hello, I have studied your case. Your flank and back pain can be due to muscle strain or renal calculi. You may need x-ray and Ultrasonography. And also check your it B12 and it D3 level. Medication like methylcobalamine and analgesic will reduce pain. You can do yoga exercises and focus on spine extension exercises. You may consult physiotherapist for guidance. He may start TENS, or ultrasound which is helpful in your case. Hope this helps. Wish you a speedy recovery.  Take care </s>
