Bartering Medical services?

[Highlander]

Medical knowledge would be one of the few trades that would continue after an event, so if you have the skill it would worth a great deal

I am not sure if having a set `reward` or payment would work, maybe the best way would be to ask what the patient could offer, you then find out what he or she has and can go up if necessary,... but would you allow anyone to suffer,..or die just because they didnt have anything, or not enough

Something else that may be worth thinking about is doing `house calls`, it will not always be possible for people to come to you, you may or may not think the risk is worth it,.. but in Medieval times people lived by doing just this
