Thank you for the query.
Usually such strong pain as you have described might be caused by a stone sticked in ureter
. This pain is described as sharp strong pain, radiating from back side to groin. It can be associated with symptoms like nausea, sweats and fever. This pain can come and go spontaneously as it only appears when little stone is migrating from kidney to urinary bladder
. Abdomen ultrasound should answer if there are any stones in kidney (but no always does) and if there is any hydronephrosis
. Urine tests might be normal when there is no symptoms, but recently after pain attack there should be some erythrocytes if you are dealing with kidney stones.
Your symptoms might be also caused by ovarian cyst
. Trans vaginal ultrasound
should tell if there are any.
If this two diseases will be ruled out, there are other possibilities, that is why full blood work should be performed, and abdomen CT if necessary.
Hope this will help.
