It's not"subclinical" hypothyroidism if you're fatigued and having aching joints. Most patients treated with radioactive iodine ablation will become hypothyroid eventually. I'd push for treatment, you'll likely feel much better once you get some thyroid hormone in you. Also, with your history, you have a 1 in 20 chance of having full blown celiac disease and a 65% chance of having some degree of gluten intolerance. Consider trying a gluten free diet, it may be the key to your joint pain.
