Hello dear, hanks for being on healthcaremagic.com.If you would have presented to me as an outpatient,I would have made the following clinical explanation- You are probably having these episodes associated with aura and the likely possibilities are: Acute onset Migraine with aura Complex seizures Some of the migraine typical symptoms are- 1)Throbbing or pulse like headache 2)nausea 3)Photophobia and phonophobia(headache worsens on exposure to bright light and sound) 4)Visual aura like seeing flashing zig-zag lights,visual field disturbances.Aura can be of other types other than visual.What you are having a hot tingling feeling throughout my body, that causes me to become nauseas, sweat and shake, and I get a sour taste in my mouth with a lot of saliva can be a type of aura,followed by headache.This can be typical of migraine. Complex seizures can result in aura followed by impaired consciousness. Whatsoever,this is acute and needs to be evaluated.Please meet a neurologist,and discuss with him to undergo a Magnetic resonance imaging(MRI) Brain and an electroencephalogram(EEG).That will help making the diagnosis and thus the treatment.I hope it helps.
