1990 , I spent five days in a hospital bed , recovering from surgery to my left eye. Yes , it was a small sliver of metal . Treatment was not imediate , first handled in Canmore ( poorly ) , the hospital couldn't do anything , it was christmas eve , the only doctor available at the walk in clinic reeked of liquor , ya he got some of the metal out and pushed the rest in deeper. A day or so later the pain and inflamation was too hard to take , so I went to foothills hospital to have it looked at , they would not let me leave till it was fixed properly , surgery , stitches , ouch ............... For two years I had headaches on that side , anytime I or someone else was grinding or using a hammer and chisel. Be careful people .
