I got my hair cut today, as it has gotten quite long and impossible to wash, I

told the barber to be very careful as I have sustained a head injury, but by hair

was quite full of knots and my head ended up being pulled in random directions.



While it was happening I felt like my head was going to explode, but after about 10 minutes it seemed to have cleared up.



Is this pulling of the hair and head enough to cause another concussion? I have been doing very well lately and am quite concerned.
