<s>[INST] My 17 old daughter has had ongoing lower abdominal pain for approximately 4 years.  Her appendix have been removed but was found to be healthy.  They thought she had endimetriosis but gynecologist said she didnt.  Her pain does not necessarily occur with her periods and is increasingly getting more severe.  Pain killers no longer work and she is unable to pick anything up, bend over or walk without crying in pain.  Do you have any suggestions please as our doctors seem to be at a loss.Thankyou,Stacey. [/INST] Hi. This is for sure that she has been seen many specialists and the conventional investigations must have been normal. There is a saying if the normal course you do not find the common reasons, it is possible to think of uncommon:: Psychological overlay has to be thought about. Maybe you should collect her urine in a glass and keep in sun to see a change in color and tell your Doctor the changes. Tablet Gabapentin may be tried under medical supervision. And it is better to go for MRI study of the spine. </s>
