Hello , Welcome to Healthcare Magic forum. Considering the details of the information provided by you, I assume that the doctors have ruled out common causes of recurrent fever like chronic infections, autoimmune illness, hematologic (blood )disorders, brain neoplasms etc. It is more likely that the convulsions are febrile convulsions rather than epilepsy or seizure disorder since they are associated with high temperature and are prevalent in this age group ( The best way to prevent convulsions is to control the fever spikes by antipyretics (ibuprofen or mefenamic acid), tepid water sponging, keeping the child well hydrated by plenty of water and if necessary using preventive anticonvulsants like clobazam as per doctors prescription. Sometimes if antibiotics(moxbro), antipyretics, antiinflammatory (ibugesic) are unable to control fever, your doctor might prescribe steroids to control the inflammation and fever. However that would depend on your sons clinical findings and diagnosis. I would also like to suggest that if such fevers recurr despite all preventive measures like hygiene, isolation from pubic places, boosting immunity with good nutrition etc then please consult an immunologist or infectious disease specialist to rule out certain rare causes like Periodic fever syndromes which is a possibility in this case. Periodic Fever syndromes (PFS) are rare conditions where fever and inflammatory symptoms re-occur regularly in patients,unrelated to infection or illness. There is usually high fever (often spiking above 40 degrees) and there can be inflammmation to the skin, throat and mouth, muscles, joints and organs and they can be usually associated with febrile convulsions.Between episodes there is resolution of symptoms and the patient usually appears well. Periodic Fever Syndromes are sometimes hereditary and often only diagnosed after years of patient testing to rule out other medical conditions. So do discuss it with your pediatrician. Wish your child a speedy recovery and healthy future. Regards
