He is 5 yrs child nd he is havin seizure since 3 yrs as u said. I wanna ask you something in this regard ?
1. Is he under proper treatment prescribed by your doctor ?
2. Is he getting seizure inspite of treatment ?
See if he is getting seizure in between treatment then u need to get the proper dosage checked by your doctor, may be u r not giving proper dosage.
3. Can i know the prescribed medicine by the dr. ?
If you r giving proper dosage prescribed and still boy is having seizure then your medications needs to get a increase dose or changed. So consult your doctor for this.
Dont let the temprature above 100°F as it may trigger seizure.
It gets subsided with time for sure with proper treatment and care. No worry.
I suggest you to visit your doctor as its a case of rebound seizure.
