I suffer from lots of psychosomatic pain all over my body, and headaches (I don't even know what to call it, its a big mess of distributed dynamic pain) are common when I'm on the down phase.
I have this twitch on the right ear just below it. I really don't care anymore about the particularities of it, its just as all the other symptomatic stuff.
You're better of not particularizing anything about symptoms.
I don't have DP 24/7 any longer and this ratio is going down month by month. I know what it is to feel normal with just some, or in many cases without any pain at all.
I intend to go 24/7 without pain.
A nice workout session does wonders, give it a try.
