Didn’t know it had a name, but totally checks out. Had it twice. Once right after we got married. I’m sure my poor new wife thought I was insane as I was screaming in a cold shower. The second time happened in Cebu and I missed a good chunk of that trip because I downed the entire resorts supply of Benadryl. According to the pain scale from an urology colleague who served in Afghanistan: kidney stone > labor > shrapnel injury.
