Is My Wife a Hypochondriac?

You're in a really tough spot. You want to help her feel better - and you to have a break from the stress of an ill wife - but if you bring it up, you're in trouble. From what I see, there's only two options. If she really is that ill, then it means your marriage is facing a great deal of stress. If she isn't that ill physically, but psychosomatically, challenging the truth of her symptoms is only going to make the maladies worse. If she's developed psychosomatic complaints, her mind has created these symptoms for a reason. Though she is not conscious of them, for whatever reason, being ill relieves some emotional pain or allows her to avoid another painful issue. And until we know what that reason is, there's nothing we can do to stop the physical complaints. It's only when those reasons are met in a more healthy way that the physical complaints will go away. 

If you haven't already, I would start by visiting a doctor to rule out a physical cause. If there is a physical problem a counselor who specializes in chronic pain might be helpful to your wife. (Check your hospital for referrals.) If there is no known physical reason, I'd really recommend you see a marriage counselor, or if your wife is willing, that she see an individual counselor that specializes in somatic concerns.
