Hi,
I swam into a Portuguese Man O' War jellyfish ... should have died by all accounts. But that is another for another time ...
The gist of it was that all that treatment got me real interested in poisonous bites .... and there are only two types of poison ...
The first causes massive red blood cell bursting ... it has a very painful onset which a person usually lives through. The cause of death is several days (weeks) later as the rbc's cell walls and debris hit the kidney ... sounds like what you had ,,, you might want to have a 'good' doctor do a renal efficiency just to be sure ...
The second type of 'poison' cases a massive making of cholinesterase (
http://en.wikipedia.org/wiki/Cholinesterase/) >in the blood stream.
This in turn 'dissolves' the cholinester, which sits between nerve cells and acts as a kind of neutralizer. The result is a rapid firing of all the muscles causing clonic and tonic spasms The end result is ascending seizures, and if the person has got enough of the poison within him, he dies of the spasms stopping his breathing of stopping his heart ...
You wife was right about immediate treatment ... where the poison is in an extremity, extreme cold (i.e. ice) can cause the poisons to break down rapidly .... but a day after the bite I would see a very good doc (this doesn't happen all the time ... he will probably have to reference books ...)
