Thank you for your query.
Something which is felt in the lumbar spine
but is not revealing in an X-ray can be further investigated by a MRI
. I suggest you discuss with the doctor and get a MRI done to know the exact condition. Without an examination it is difficult for me to give any guidance.
I hope I have answered your query to your satisfaction.
Wishing your daughter all the best.
