Chronic pain can affect memory, but the mechanism may not be stress.
There's a study available (http://www.anesthesia- analgesia.org/cgi/content/full/104/5/1223) that spells out the case that pain affects memory by dividing attention.
Also take a look at http://www.ncbi.nlm.nih.gov/sites/entrez? Db=pubmed&Cmd=DetailsSearch&Term=9755349[uid].
It's entirely possible there is a mechanism by which pain affects memory thru the hippocampus, but my hunch is that the distraction effect would dominate.
