Glad to hear you're doing well. Standing in cold water was likely the best thing for it (clean it, reduce swelling AND most importantly, allowed you to fish).
The plantain Uncle Jesse mentioned is quite common. goes by a number of names, also called Soldiers Herb (has coagulant properties, can be used as field dressing). Best natural item to use in the field IMHO.
So - errr ... what happened to the fish ?

Darrell,
