I Monica. The only time I had difficulty swallowing and felt like I was choking was when my levels were so high and my thryoid had increased to a huge size that he obstructed my ability to swallow which really bothered me and drove me nuts. You could see the largeness of it all just be looking at my neck. Actually, when the endo maps it out it looks more like a huge, huge bowtie. I don’t know if this has been any help. Sounds like you need a blood test.
