@Mattchsticki have a sickness that's much milder than that. basically, every day at a certain time, i get episodes where i feel tingling and a funky nervous sensation in my left hand and left feet. it does it for about 1 minute and then when it stops, i'm good to go for the rest of the day.
if i somehow mess up this episode, by doing "something" wrong with my urethra, i will stop the tingling. if i do this consistently for a couple of days, i will get headaches
my theory is that this tingling lets out pent up energy that's in the sensory part of my brain (particularly the left hand and feet). if i mess up the process that happens daily, this energy will turn into headaches
i've explained this to doctors and they have no fucking clue what i'm talking about. they say i have schizoaffective disorder, which is basically saying that i'm delirious and that i'm unconsciously making it up
