Your symptoms are very characteristic for kidney
stones which are migrating downward a ureter
Both CT scan
and X-ray may not reveal kidney stones, as it is very hard to visualize them in a urinary tract
(especially in ureter). Urine tests needs to be performed.
Sometimes a pain radiating to a toe can appear when there is a spine problem (but this doesn't usually cause vomiting
or abdomen pain)
Treating kidney stones you should drink a lot of water, take a hot bath, be more active so the stone may be moved down and removed with urine.
Some myorelaxants may be prescribed by your doctor.
Hope this will help
