Abby, Go see your neuro or internist. A physical therapist should "fit" you for one and then your insurance will pay for it. I'm having to do that now because of neck/jaw weakness too. Yes, they do help.

The U-shaped pillows help when you sit in a chair. You can get those almost anywhere, like AAA's store.

Things like these and others like shower stools, chairs in every room, etc. do help.
