... what would be causing me severe stabbing pain in my left groin area. It is almost like sciatic pain only in the front. it is very sharp and is not continuous. But when it happens it is short, almost like a wave and can go on for an hour or more at a time. Had mri done in this area, nothing showed up. Kidney is not even there anymore either. Removed 2 yrs ago. This pain started about a year ago. Any ideas or help will be GREATLY appreciated
