My Mother is 77 years old, started having lower back pain on both sides, the pain moved to the front lower abdomen, no fever. All started after dinner, just vomited. Wondering if it is kidney stones. No problem urinating yet. Worried about the constant pain in lower abdomen now.
Hi I am Chat Doctor. .  In my opinion it is probably a renal stone or gravel and the pain is usually referred to lower back, it is very rare to have such pathology on both kidneys at the same time unless she has a past history.  She may increase her fluid intake, avoid high protein and salty meals, proximal or allopurinol sachets , phosphorus solutions and eating oxalate rich food will be helpful in most of the cases.  If pain persists I recommend laboratory investigations like urinalysis, BUN (blood, urea and nitrogen) , creatinine levels to diagnose these stones, the best diagnostic tool is U/S abdomen and pelvis to know site and size of such crystals.  Hope your mother feels better soon and if her symptoms propagates visit her nephrologist for proper evaluation and management.
