[|Human|] Hi my 4 year old son has been complaining about back pain for the past few days. It comes on suddenly and sometimes stops him in his tracks. We have noticed it usually happens shortly before or after urination. It lasts for a few minutes and then he is fine. Also about 3 weeks ago there was some blood in his stool. I called our pediatrician and said to keep an eye on it. He had no other problems until now complying about back pain.
[|AI|]  Hi, From history it seems that he might be having renal colic giving this problem. There might be having urinary tract infection or renal stones. Go for urine check up for pus cells and red blood cells.If you require go for ultrasound of abdomen. Passing blood in stool might be due to absolute constipation as while passing hard stool might give soreness in lower rectum producing blood. Give him plenty of water. Ok and take care.
