[|Human|] My son is 16 years old and weights 70.5kg. He has been having mild to severe pain in his lower abdomen (shifting from left to right) and lower back pain since early December.  He has done an ultrasoud, ct scan, urine test, several blood tests and several xrays.  At one point they said he had sacreolitis and after 2 1/2 weeks of taking indomethecian they said he in fact did not have this disease after all and told us to stop taking the medication and have still left him undiagnosed.  Today he is once again in severe pain on his right lower abodomen and lower back, he has taken advil all yesterday and still today with no relief any suggestions??
[|AI|]  Hi. Thanks for your query and an elucidated history. If the area of pain is constant in position I would advise you to request for an MRI of the whole spine, details of the thoracic region as this can get us the reason. This is not uncommon but rarely diagnosed. He has already undergone all the other tests. Also consider the IBS- irritable bowel syn Chat Doctor. Colonoscopy. Color Doppler of abdomen to see for the blood vessels, any obstructions or so. The diagnosis is always to be sought after as then only a proper treatment is possible. A trial with Gabapentin, antidepressant may help.
