I have lower back pain.  It feels heavy and aching.. in what I would think is the kindey-region although I dont think its kidney related.  I also feel nauseous, retching but not actually vomiting.. just feel really sick.  Nausea seems more acute on movement. I am female, 25, with no known health problems.
HelloThanks for query. Low backache with nausea can be due presence of stone either in kidney or Ureter and needs to be ruled out. Please consult qualified Urologist for clinical examination and get following basic tests done to confirm the diagnosis.1) Urine routine and culture.2) Ultrasound scanning of abdomen and pelvisFurther treatment will depend upon result of these tests and final diagnosis.
