My mother is in a assisted living apartment. She has three daughters we talk to her every day see her quite often, bring her food etc. She is always having her worst day saying pain so bad she just can't live another day. She calls doctors makes appointments, goes to ER, will call us many times a day wanting something done to help her. Doctors always find nothing wrong. Can this be a form of DEMENTIA? She is driving us crazy, and spending a lot on medical treatment.
I read in your profile that your mother is depressed. I know various pains can accompany depression, but I don't know how severe the pain would be. I wouldn't consider dementia unless other things (loss of memory or reason) are pointing to it. I would make an appointment at a pain management clinic. I hope you can find some relief for your mother. I know another appointment is a dread thing, but if it helps solve the problem, it would be great.
Just a suggestion.
Go with Jessie's suggestion and get your mother checked out. It could also be that the pains are nonspecific so the doctors aren't able to attribute them to anything identifiable.
