Chronic pain and pregnancy..How to deal?

I've been through two doctors within the last two years..So far all I have found is I have ulnar neuropathy in both arms...But no cause???? I also have severe TMJ which is seriously terrible right now, I can't eat anything that has to be chewed. I go into my doctors appointment on Thursday. Is this something I should bring up to my midwife, or should I go to a regular doctor. I am in the middle of switching primaries because he's not helping and hasn't in a year..What do I do if I can't eat!? I'm so hungry and have so many cravings for everything but I cannot eat it :( the pain is unbearable. I don't deal well with mouth/head pain well..Its worse than natural labor for me. Anyone find relief for Severe TMJ!!?
