One cause of lower abdominal pain that radiates down to the groin and leg are kidney stones in the ureter or some other disorder that causes spasms in the ureter. Certain liver disorders (hepatitis) are associated with ureteral stones.
Hi there!
Well, without a detailed clinical evaluation it would be difficult to determine the cause of your symptoms. Possible causes that may need to be considered include GI/ GU infections/ inflammations, growths/ masses such as renal calculi, neuro-muscular causes, vascular causes etc. Increased leucocytes in urine and fecal overloading could be responsible for the symptoms as well. I would suggest considering a detailed evaluation by an internist initially and depending on the cause diagnosed/ suspected, it can be managed accordingly or specialist care may be sought.
Hope this is helpful.
Take care!
