At what point should I be concerned ? I’ve called the on call nurse and waiting to hear back is driving me crazy!

He’s had 4 episodes in 3 hours. He’s acting mostly normal. He’s lying down quietly now which he NEVER does. Always on the run usually. He doesn’t have a fever or anything.

Any insight besides giving him water ? And yes, I know that the majority of people who read this are not doctors or nurses. Just looking for piece of mind while I wait.

Thanks !
