19M.
Every so often I'll feel bursts of electric pulses. I feel them in my upper head, the tip of my tongue, my palms and the soles of my feet.
Standing up triggers them. Turning my neck from side to side, especially to the left, also triggers them. Often they just happen on their own, though.
Each pulse is a fraction of a second, but they come in bursts of three to five.
I can hear them, they sound like bursts of static, not too loud.
They're not painful, just distracting.
