I had fallen of a roof 20 feet high. While traveling downward i reached out tograsp the aluminum ladder. I CONTINUED TO FALL SLIDING MY HANDS ALONG BOTH SIDES OF THE LADDER. 8 FEET FROM THE GROUND MY WEDDING RING GOT HOOKED ON THE PORTION OF THE EXTENTION LADDERS MID SECTION, STOPPING MY FALL IMMEDIATELY. I left the job site with a coworker. When I sat in the truck I felt my head explode in pain! I fell to my knees in pain worse than any migrane.Severe pain that set my head "screaming". I went to MGH and had x-rays, spinal tap, full body MRI, and multable blood work. I was told, there was nothing they coul'd do. .Every time i'de sit the head and neck pains returned. stand, and the pain, again returned. The next morning I called my brother to tell him i was suicidal with pain. He told me his son had been diagnosed by Spalding as bi-polar. He said his son went Dr Rom Amato and never used meds again.I went, and I too was cured from my HELL! Thanks DR Amato. God bless you . John Raboin
