(Concern) I have a slight pain in my lower left abdomen.

Since I arrived at work in the morning, I've been feeling a slight stinging sensation, or maybe a feeling like being pricked with a needle.

A stabbing pain occurred intermittently. It was quite painful for a brief moment in the morning, but since lunchtime, it has been...

I'm almost okay now. I don't know why this happened.

Last year, my urinary stones recurred, so I underwent extracorporeal shock wave lithotripsy to break the stones. It feels just like that time.

It also feels completely different. The recurrence last year was after 10 years, so I don't think another cyst has formed in just one year.

It doesn't feel much different now, but what could be suspicious?
