Hi ! You have not mentioned any history of trauma and the cause of laceration. The pain abdomen could be due to any intestinal infection, if she eats from outside. The cyst
in the kidney
could be an incidental finding unrelated to the present problem of yours. I would suggest you to go for some basic investigations like urine and stool test
. If any kind of infective organism is found, then you may get relief after taking the specific medication. If the symptoms increase in intensity, you should go for an ultrasound
abdomen for your wife in consultation with the treating doctor.
Wishing your wife an early recovery.
