I would flat out state to the doctor (even loudly/interrupting him if I had to), "You aren't listening". What could it hurt?

Have you had medicine or care that helped? Could you explain that to the doctor so they'll know what has worked?

When I was doing a lot of hurting I did a lot of reading (children's novels :-) and that helped some to keep away "Them" and give me (and those around you) some rest. We can only focus on one thing at a time so if you can get interested in something else, They will have a harder time getting to you.
