Dear sir, it really sounds like kidneys problem especially considering that u ve already had something similar, but it doesnt need to be infection only, it can be ureteral colic or hydronephrosis
. Beside this a plenty of disorders can cause such a pain. The most common are cholecystits, appendicitis
or any intraabdominal infection
. If you have any other symptoms such as fever, chills, nausea
, blood in the stool or urine i suggest you to go to hospital as soon as you can no matter you dont have an insurance. If infections that i ve mentioned before are misdiagnosed there could be serious complications.
Wish you good health, Dr. Ivan Romic (Rominho)
