Tho hypo-thyroid isn't my main issue these days [I've others], I did start to have hypo thyroid issues about at your age +/- a year or four? I was lucky with my GP at the time who did a FULL thyroid panel on me and was quickly put on synthroid...It then took a few years to tinker the dosages to just rite.
But if only the basic thyroid & T-3, T-4 are done, not a whole lot would show up. To make it easiest on yourself? Be sure, if you get the test done, to FAST and have it done early in the morning! Otherwise, like other basic tests, such as simple blood sugar tests, the #'s will be skewed a little to a lot bit.
I'd really hate to have you going from specialist to specialist tho? A really good exam of your ankles does appear to have been done and no visible 'structural damage' seems to be present, Consider that A GOOD thing?

Having a CLUE as to what they are doing is half the battle in my book>
I understand the anxiety. I also understand as do all here that the PAIN and fear it all creates is something most folks [unless they experience it] DO NOT GET! It's like cancer? Since I've that too, it's surprising how many cancer folks ask ME about the neuropathy stuff! Mainly because their docs don't do anything other than say 'live with it'. We don't have to. BTW? My cancer came long after my PN!
You are going thru the beginnings, it sounds, of a good diagnostic work up. Don't worry about it all until most stuff is eliminated. The process is one of ELIMINATION.
So hang in there and keep getting those tests done! Knock things off those lists! Have faith, and maybe it IS something simpler than immune issues or those other horrid thoughts you've been having. Save them for later! Work on diagnosis, living right and hugging your kids and your hubby! Every blessing in this world is likely right there to hug! Think positive things for now and get stuff done as best you can! Special thoughts and good ones for now - j
