Kidney stones have been a painful reality for Ed Feiteira, who lives in Stoughton.
When the stones would form, it would feel like back pain, but then eventually move down below his waist. He would usually pass the stones in his urine, but once a larger stone caused pain so severe, he had to go the emergency room, he said.
“When you have a pain deep inside and you don’t know what it is, it’s scary and it doubles you over,” Feiteira said.
Kidney stones form when calcium and other chemicals in urine become too concentrated and crystalize. They can block the flow of urine and become very painful. If stones become lodged in the urinary tract or kidney, surgery can be required to remove them.
