Pressure...one of my first symptoms that I ignored, or just attributed to how much weight I'd gained. I thought it was fat and soft tissue on my neck that was choking me. It started with just 'sometimes' when I'd swallow a certain pill. Then, it went to everytime I'd swallow pills. Then, just certain positions (i.e. reclining). Now to all the time. I'm an anesthetist by trade and I can correlate it to someone holding 'cricoid' pressure on my throat.
Interestingly, over the last couple of days, I've noticed that when I put my head downward to read, or work on the computer, or cook...I have this muscle fatigue feeling in my right neck and shoulder. I don't know if it has anything to do with my big fat thyroid, or the tumor, or just the stress from finding out that I have the cancer. Interesting note to self.
