Had grand mal seizure last night, after I came too. I needed help to bathroom & got sick for 20 minutes or so. I have never had that happen before.
Not to mention that if you have any form of aura, they can mutate. If you research the topic then you will see that there are many types of auras. My standard is always the deja vu, but I have also had the additional kick in the gut (stomach aura). Auras are known to mutate. It is a possibility, but rare that your seizures will as well.
Nausea is one of my main symptoms that I'm having a bad seizure. My brain fires, body releases adrenaline and that starts the nausea. This is the worst and is very hard to stop. Cannabis is great for prevention of most of these big seizures, but doesn't work well to stop them. I usually have to take Ativan to stop them. Recovery is slow and sometimes I'm wiped out for days after.
I haven't gotten sick after coming out of a seizure.
Hopefully you're ok Deborah. Without realizing the aura, seizures like you mentioned could leave results on me. What John presented is true. Even if it's not the trigger, stomach can be involved in a seizure. Eating too much and/or too close to bedtime, does create problems which can also trigger a seizure with headaches resulting for me. It is all tied together courtesy of our nerves.
