The 4th GP I saw finally listened to me and actually took me seriously. He looked and felt my neck and said I need an ultrasound as it's swollen on one side. He referred me to an endo who I had searched out myself beforehand and who I haven't seen before. Therefore I'm sure it will be at least a month but probably more before I get the appointment and ultrasound. My throat is sore all the time and my neck feels uncomfortable/full. My voice also seems weird as if I had a cold all the time, several people have commented on it. Obviously I'm a bit worried and wondering if I should pay £200 to have a scan soon at my local private hospital? I have a small child and I guess that's the main reason I think what if I wait too long and something is missed etc etc..... My TSH last week was 3.6 and FT4 10.8, is it possible that there is something serious wrong without showing up in these tests? I have never taken any thyroid medication.
