Yes, I have a mother that does that. She's always seems more interested in the health of the nursing home patients then her 3 daughters which have lupus. I said to her I'm going to bed early because I'd been up since 4am with my back aching..she said well I've been up since 4.30am. The thing is with Mum is that if she can divert her sympathy towards herself or others she doesn't have to deal the feeling of helplessness towards us...if that makes sense. They think by telling us about others people's illnesses it may in someway make us feel less alone. It's annoying especially if you're having a flare. Try to think of something funny when you speak to her...like her with a beard. Don't let it bother you. You've got enough to handle. Good luck.
