Cancer Survivors Network

Hi. My name is John and I am a first time poster. I had my TT 3 years ago after having surgery to remove a benign tumor on one side that turned out to be ptc. Recently I had a ultrasound which showed small growth on one side. 7mm by 3mm. About two weeks after the scan I began feeling sick. I have been sick for five days now. I've had swollen lymph nodes (only briefly) in my neck and a tightness and numbness where my thyroid used to be and I've been exhausted. My thyroglobulin has always been between 1 and 2. It's 2 now. My doc wants me to do and rai scan and I'm sure she will want me to do another ablation. She said the ultra sound showed nothing else in my neck and my nodes looked good. The sudden numbness in my neck is driving me crazy. Should I do the RAI with thyrogen or get a PET scan? She seemed unaware of the thyrogen shortage and I had to make calls to locate some. The cancer center had it on back order and was just going to wait but when I pushed the issue they called a local hospital and found some. Is that strange? I guess I'm just tired and freaking out a little and could use some advice!
