One late afternoon,about 15 years ago I walked down to our mail box at the end of our drive (about 900 feet from the house). As I approached the box, a neighbors rottwieler cross came out in a very threatening way; he was snarling and jumping up at me as I waived my western hat in front of me and yelled at him. I had nothing to use as a weapon except my work style western boots. As he became more threatening, I decided I was going to have to fight him with what I had, so decided to try for a decisive first blow and timed it to kick him as hard as possible in the family jewels as he jumped up. When I kicked him I thought I had been shot in the upper leg! A sudden extreme pain, but he must have felt the same as he whimpered and walked back home. I took about 10 minutes to get back home hobbling along holding my leg with both hands.
I could see nothing on my leg but the pain was really bad, so
I just sat the rest of the evening. The next morning I had a baseball size knot on the front of my upper leg. It was still really sore but I struggled through work for two days then went to see my next door (1500 feet away) neighbor and family Dr. When he saw it he laughed and said, wow, you tore that sucker plumb loose--the major muscle in the front of upper leg. It had rolled up, making the big know and leaving a void below it.
He said we could re-attach that muscle with surgery, but I would be in a full leg cast for several weeks--I said no thanks.
The knot has slowly gone down over the years, but is still about 1 1/2 inches wide, 3 inches long and raises about 1 1/2 inches. It only gives me trouble when really working it, such as climbing a steep hill.
The dog owners were a really likable young couple who were very good neighbors and in several years that was the only time I ever knew of the dog being out, so I gave them no trouble over it.
