I keep a list of all neurologic symptoms...bladder/bowel, balance, pain, numbness, cognitive problems, eyesight, etc.
I list the date of onset, what I notice, and the date it dissipates. Sometimes the list is looonnnngggg....
It assists me during my exams with my neuro...gives him a timeline of what has been occuring. Then I usually get a lecture about the need to call him when these things happen.
It'll help you, too, so you don't have to remember what the heck happened and when...
