Get renal studies.: This might be nonspecific back muscle pain due to your being overweight or possible something more serious, like herniated disc with nerve compression or possible kidney issue, although kidney/ureter pain would likely be lower. You do have "burning" right flank which still can be kidney involvement. It might be a good idea to see your doctor to get your labs looked at, and an exam to find out.
