DEVGRU Operator Went Through Hell Week and BUD/S With Undiagnosed Kidney Stone and Diarrhea

Froehart described experiencing severe abdominal pain during Hell Week that Navy medical staff misdiagnosed as IBS and treated with laxatives, causing him to suffer diarrhea during the remainder of training. He later learned through proper diagnosis that he had kidney stones lodged in a scarred ureter, the same condition that would eventually cost him his kidney and end his DEVGRU career. The misdiagnosis occurred multiple times throughout his career including during sniper school where he took a marksmanship test while on Vicodin and achieved the top score.
