Critter,

Welcome to NeuroTalk.

It sounds like you are having struggles with anxiety. Maybe the visual of riding was too much stimulation.

Did you get any medical diagnostics at UPMC ? Micky is a PhD not an MD. What PT did he prescribe ?

You may have a thyroid or other hormone issue causing your sweating. How do you know the sweating is not starting while you are asleep ? Do you wake up but snooze/doze and the sweating starts ? Have you tried just getting up as son as you wake ?

Do you have a neck injury ? A shoulder injury and concussion suggests a substantial trauma to your neck. Cervical inflammation can disrupt blood flow to the autonomic nervous system and cause disregulation. Various sleep postures can magnify neck inflammation.
