frustrations. It does seem as if you have doctors who are doing some of the correct tests. I myself can't say that YOU have PN or not tho.
I suggest that you read all the 'sticky's up at the very top of the forum. I strongly urge you to lake a quick look at
www.neuroexam.com as it's about how doctors go step-by-step in their testing and for details of the processes
http://lizajane.org The latter has been put together by LizaJane and others here have contributed to it as we each came here thru different PN causes or effects. Also read some other folks' posts, you may find that there are answers to some of your questions there.
Also be sure to get copies of your tests or summaries and blood work - putting that info into Liza Jane's work sheets will help you get a better handle on what might be going on.
Make no bones about it...pain is definitely a GIVEN here!
As for posting, don't worry, it gets easier! - j
