re-reading about your iron supplement....I too think that whatever he intended to give you was probably not enough to cause damage however.....was it the same doctor who did the procedure and also saw you in the ER?......
I will tell everybody this:....never assume that there is good communication between doctors , between doctors and nurses etc etc....ALWAYS be aware of your health situation and don't hesitate to ask questions....docs do not have access to every bit of info on you and they also forget things......
This is very true. When it comes down to it, you must always look out for yourself! Don't be shy, timid or afraid to ask "dumb" questions.
