Re: raised rash
The autonomic system may be effected during his seizures, causing the goosebumpy skin - autonomic seizures or complex partials with autonomic features can cause a bunch of things that are invountary responses to a lot of body systems.
I turn bright red on my face, white around my mouth and limbs, blue nail beds (with ok oxygen levels- shouldn't be that way !!), and ice cold after a 'hard' complex partial with the autonomic symptoms thrown in. I've been told I look dead. Breathing gets shallow enough to set off apnea alarms at the hospital.
So many symptoms can be part of the seizure; autonomic symptoms may not show up on an EEG if it's caught during one, since the part of the brain responsible for autonomic activity is very deep, and the superficial electrodes can't pick them up.
