You definitely do not want to have one of these! I was getting ready for work last Friday and suddenly I'm in serious pain - in my back, on the left side, below my rib cage. It would not go away. In fact, it got worse; came right through to the front like a kick in the groin. I was home alone and didn't think I could drive. I called an ambulance and ended up in Surrey Memorial Hospital for the day. Had a CT scan and about 2:00 p.m. I was told I had a kidney stone, given lots of pain killers, told to drink lots of liquids and sent home. I passed the stone at about 9:30 p.m. and the pain was completely gone. I'm supposed to call a Specialist on Monday. The Ambulance Crew and the Hospital Staff took very good care of me. I went to Costco on Sunday and bought $25.00 worth of pens (nice ones) and gave them to the Staff in the Emergency Ward of Surrey Memorial Hospital.
