Thanks for the query to H.C.M. Forum.
As you didn't mention the exact site of pain in abdomen , so very difficult to make any diagnosis .
But infection in the urine and raised T L C is a clear indication of renal infection( Kidney
or urinary tract infection
Since T L C decrease so this is good thing.
In my opinion get in ultrasound
of urinary tract system , urine culture and drug sensitivity tests.
Also get in serum creatine
and blood urea test to rule out any kidney involvement.
Consult an urologist
and get his opinion.
