Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice. What you described is a typical seizures, i.e. fitting followed by tongue bite, and muscle weakness. There are a lot of hazards of having fits, i.e. falls, roadside accidents, getting wounds and a lot more. There is a hazard of death as well though that is an uncommon. So getting fits again and again is always risky but luckily a lot of medicine can work very effectively to control seizures. So I would suggest you must not waste any more time to see doctor who should do some test if there is any reversible or precipitating cause and then he can prescribe you medicine that would hopefully control his seizures. Hope I have answered your query. Let me know if I can assist you further.
