Thanks for the query to H.C.M. Forum.
You are a 25 years old MALE or FEMALE ? This is important as few disease in male & female are different as far as concerned about lower abdomen .
Your urine report is normal and this can't be the reason of lower abdominal pain
. Only amorphous urates are positive means may be stone or calculus in urinary tract
system so this may be the reason of pain.
In my opinion write down complete history of illness as where is pain , left side , right side , below pubic area, burning micturition .
Good luck. Dr. HET
