21yo DS went kayaking (and I assume swimming) in the river, according to DD (DS isn't up to talking atm, I'll ask him later)
He's now being violently sick, repeatedly, even though there is nothing left to come up. His body, really, really doesn't want what ever is in him to be in him! Does this sound like something caught from the river or just a general sickness bug? Does it make a difference in how I can help hiim? I've asked him only to only have sips of water.
The same thing happened 5 years ago when he swam in a ford which is now well known to be polluted.
