Better to find and fix than to go undiagnosed.

Yes, low thyroid can do a lot of that, too. So many things have overlapping symptoms, and often go together. Did you already know you had thyroid disease and just needed dose adjustment, or is it a new diagnosis for you? Here is one of the best places for thyroid info:

Anemia can be due to low iron or low B12 or both. Did he say?

I hope you will have improvement once these things are treated! Let us know what more you find out and how you are doing. You will feel better!

Celiacs with muscle weakness
 

Have you doctor test you for Myasthenia Gravis. You would not be the first person to get diagnosed with Celiacs and then later get Myasthenia. Also you check to see if your problem is totally gluten or more yeast than gluten. But if you never eat any gluten products or bread or pastry again you will live a better life.

The back of my right hand and wrist just flared up in the last few days. It's red and inflammed and dried out and bled in one place. I have to cool it down with very cold water every so often. It's nearly in the exact same place where I was experiencing odd neuro symptoms (discomfort but not pain).

It looks a bit like eczema, which I have never had before. I'm try to figure out if there's a connection between PN and the eczema (if that's what it is).

I've been off gluten for many months (as far as I know).

My B12 results (and other B levels) are due any day now.
