yes, I was injured at birth due to forceps being used to pull me out and when doing so the forceps caused a blood clot to wrap around all the muscles on the left side of my neck. When I was eight years old, (due to a 4 inch difference in the height of my shoulders, the doctors removed the blood clo, splicing eighteen muscles and severing the mastoid mustle. Now I am almost 67 years old and have never had any problems, but since I m hearing that my age will now play a part in the health, so is there anything that would cause me any problems later in life?
