I had a CT scan done of my head and neck and it showed that my thyroid didn't look right and that my lymph nodes in my neck were all swollen. The follow up ultrasound showed that I have a cyst on each side of my thyroid, (size unknown), and the radiologist states that they are unsure if the other things they saw were my lymph nodes or not so I now have to have another CT scan with contrast. My PCP isn't concerned but I am constantly tired, fight to stay awake throughout the day, and my depression seems worse. She said my blood work she did was all normal so she's not worried but I am.
