I am taking Nature- Throid for low throid. I have had multiple nodules for years, never a biopsy, but I get a yearly ultrasound. Over the years they ve gone from 5-7 mm. Over the last year, the front of my throat by thyroid and vocal mechanism has become swollen and abnormal looking. My main Dr. Has not expressed concern, but now it s gotten worse and swallowing is more difficult. My neck is fused from C4-C7. I thought that was the issue and My Dr. was ignoring it, but now I m not so sure. Don t know what to do next.
