is at the beginning. PN can have many causes (how many did we count up to on the old forum?). I suggest you take a look at the lab tests for sensory PN on www.lizajane.org and start with those. You should have all of them at one point or another.

One other suggestion: It's probably easier to help if you keep all the info in one thread for now. Otherwise people clicking on a new thread may miss what you've said in the old.
