Hi 04NeuroAtrophy+, and welcome!

I'm afraid I can't suggest anything helpful for you except to say that it sounds as if your neurologist is trying to find out what's going on--and hasn't indicated that you're just making it up.
Sometimes family members find it convenient (for themselves) to say you're "just faking" but please keep in mind that they probably don't want to have to be concerned about you or to make special arrangements for you, as they might feel they would need to do. They're protecting themselves, without thinking about how much they're hurting you with their attitude.

If they think you're just making it all up, they can go on with their lives and ignore you. Very handy for them.

There's not much point in debating the issue with them. All you can do is proceed with your neurologist and the tests you might need--possibly go to other doctors if that seems called for--until you can come up with some solutions.

Other people will probably come along with more helpful ideas for you.

Just in case some of your readers don't know these abbreviations:

DJD in your Profile - degenerative joint disease
OSA - obstructive sleep apnea
