Two days ago I was electrocuted at work while on a ladder. The 347 volt lighting circuit I was working on was energized and the fixture wasn't properly grounded. When the wiring I was inspecting came loose and struck my hand I was stuck by the wire and could not let go. It must have been an instant since the exit wounds on my thumb and index finger are considerably minimal, but it felt like ten seconds. What eventually broke my contact with the wire was that I fell off the ladder and landed on my coccyx. Once my eyes regained focus I looked at my right hand and saw and smelled the burn marks on my thumb and fingers. The locations where I was feeling pain was in my coccyx, my thumb and index finger on my right hand and my kidneys. I checked my heart rate and dressed the burns on my fingers. The pain from my kidneys soon took over and I decided to go to the walk-in clinic where my doctor is. I told him what happened and he suggested that I go to Emergency and get everything monitored properly. While in emergency I was sitting upright in a hospital bed and the pain of my coccyx was about the same as the pain in my kidneys. The doctors took blood for tests at 2 different times and also took a urine sample. They took x-rays, I was on a heart monitor and EKG monitor. While in emergency they didn't do anything but look at my hand and ook for other electrical burns. The doctor noticed that my L1 had an old fracture that healed perfectly. End result they were not able to diagnose the reason for sore kidneys, they said I was lucky and that my heart rate is regulated and gave me a perscription for 20 T3's for the pain and to come back if things got worse.
