The rib pain is the more painful part of Fibro for me. I ge tit failry often and it does last quite awhile. For me, the rib pain seems to be most acute when I am stressed.....less so because of activity. When my rib pain is apparent I tend to not breathe properly (because of the pain) and it seems to make it worse...Keep making breathe through the pain....
I use Trazadone at night. It is an anti-depressant that helps people sleep. I have been using it for 3 years and not had a single night of restlessness. Ask your doctor about it....maybe you too can sleep well.
I cut out most of my meds, except Cymbalta (once every morning) and am down to a half pill of the trazadone(at night).
