I read the replies to your post in the chronic pain section and thought I should add this.

You should be careful about how your local doctors/hospital/county regards people who make repeated trips to ER complaining of pain and seeking help.

This can often be interpreted as drug seeking behaviour and that is definitely something you don't want in your medical records. ER departments do get lots of dependent drug users who are seeking drugs rather than 'genuine' pain patients who are desperate. I know your PCP has mentioned you can go the ER but I just urge you to be careful in case it presents a difficulty later in your marathon journey with CRPS. However genuine you are and regardless of having a proper diagnosis, its easy for one doctor to form a wholly different and unsubstantiated opinion of you - then it's virtually impossible to get rid of that lingering stigma. It's just another really hideous feature of how the medical profession can unfairly work against genuine, decent people.

I just urge you to be cautious and if you can, sound out the position locally to make sure you don't innocently make subsequent completely legitimate treatment harder to get.
