I have had pain in my lower back in the kidney area for a couple weeks now. No other issues.I am a woman of 71 years old and do farm work , shovel , rake, lift 50 lbs bags and goat kids. I may have just strained my back but have not had this pain in this area before. Thanks
From history & considering your age, it seems to be musculoskeletal pain. Clinical examination & ultrasound of abdomen needs to be done.
