Hi. Thanks for your query and an elucidate history. Getting unconscious after stomach ache along with the findings of CRP and Pus cells you have noted is highly suggestive of septicemia due to severe urinary tract infection. He has continuous high fever, the attack is recurrent. I would suggest the following in such a situation:: MRI of the brain to find out any problem in the brain or its coverings. Spinal fluid tapping and to send it for chemical analysis. Culture and sensitivity : of the blood, urine and spinal fluid. Routine blood, urine tests must have been done- these need to be done repeatedly to review the progress. Also to follow kidney function test. Get an opinion of the Urologist, Neurologist . get the treatment as per the reports of C/S examination.
