Bi-polar and chronic pain

Hello everyone! I am usually on the chronic pain forum, but figured it would be good for me to post this here as well.
So my husband told me tonight that he read that people with bi- polar suffer with chronic pain? Has anyone heard this? He proceeded to tell me that these people exaggerate their pain but don't know they are doing it. I guess the neurotransmitters for both conditions are in the same place as each other, so the brain can't distinguish between the two. I just don't know what to think about this. The thought that I am exaggerating my pain ticks me off as I would never do that. And why wouldn't any of my Dr's mention this to me? All of my Dr's know I suffer from chronic pain and being bi-polar, so if they exaggerate each other wouldn't one of them tell me this? What do you think about this? Have you heard this before?

Maybe you guys could help me. My wife suffers chronic pain in her back L5+L6 gone... She is currently being treated at a local pain management office. She also suffers from addiction to the pain meds that cause her to take more than is perscribed and then she eventually runs out... So after the withdrawls for a couple of days I usually get my loving wife back for about a week. Then she gets her refill and BAMN back into manic mode. I can read it like a book. I know whats coming. She takes percocet 30 4 times a day or at least thats what she is perscribed its usually in the 6-7 times a day range. She totaled our car on 2/01/12 and now she is seeing she has a problem. I was wondering if you guys have had any reactions to varoius pain meds and how it affects BP. And yes she does exaggerate her pain a great deal. she also denies being bipolar even after being diagnosed twice. We have three children 2 boys and a girl. She confided in me yesterday that She knows she is not a stable person. but refuses to admit bipolar. dont know what to do anymore. Its hard to help some one out of a mud puddle if they just want to lay in it...
