Finally did get a call. Nothing shows up on ultrasound, which they told me after I called several times. TSH was over 5, so they're increasing levothyroxine again, third time this year. Thyroid Antibodies were "very high" meaning I have hashimoto's, a condition where the body attacks the thyroid. I asked, and there's nothing that can be done to make things better, they aren't looking into the swallowing further and seem to pretty much not believe me about it. I need a better primary doctor
