This brings up a host of other possible issues as well.  Is there a good, comprehensive medical book for treating yourself for more than just first aid?  I have heard good and bad about the book "where there is no doctor".  Any medical types ever read it?  What do you think?  I have had quite extensive training in wound management and treating combat type wounds and injuries, but little in how to find the right meds when I am traveling in a third world country or how to use them.  I am often on my own in countries where I do not speak the language and the medical care is suspicious at best.  Any thoughts guys?
