But, I'm not worried. They are the results of concussions and falls from ages ago. You just have to play back your life's memory bank to recall them.
Most likely, these particular type of spots will not change in the future.
It's best to be patient and go back as requested to ease your mind of further possible problems.
My advice, from one who has been tested far more than I'd like to recall? GO! Get tested ideally rule something out and get that issue off of your list of possibles! You'll sleep better knowing one way or the other, truly.
