Thanks Marlene
Sorry, not sure why my same post keeps showing up?? That's right, they did not check B-12 or any of the others that you listed. Thanks for the suggestions!! I'll be sure to ask about getting those checked.
Also, I just found out that my grandfather and other relatives had rheumatoid arthritis...so I guess that is a possibility as well.
I also notice that are levels started dropping right after we moved into our new house which is on a well. So maybe we'll have to run some heavy metal tests to see if anything pops up.
