<s>[INST] Hello, my mum has got lower back pain at the right side. she had a urine test that showed no problems, she has no nausea or vomiting and no urinary disorders . could she have a kidney problem? by the way, she s always had pain all over her back that comes and goes but this right side pain has been for months so far and more frequently. what doctor should she consult and what analyses or imaging should she have? Thanks in advance. [/INST] Hello. Welcome to Chat Doctor forum. Locallised pain in the right lower back can be from kidney, but is not necessarily so. The causes can range from simply musculoskeletal to visceral. You need to tell us in detail, the character of pain. Priminarily she can consult any experienced nephrologist, who will rule in or rule out kidney problems. The investigations required by her will be:1. USG -PUB region2. Complete blood picture3. If required - Abdominal CT4. Lastly MRI-spine if no visceral cause is decided. Take care. </s>
