There are two reason why he needs to see a doctor:
1. The fact that he had a seizure and there is a chance of recurrence in potentially harmful places (like while driving, operating machinery etc.)
2. The rahs that has not improved with OTC products, this could be related to the seizure, and this would merit a definite investigation for the cause of the rash and the seizure.
I would urge you to ask him to get a medical opinion at the earliest,
Do let me know if you need more information, please remember to 'accept' the reply if you find it useful; a positive rating & a bonus at your discretion would be appreciated,
