Hi there- I had an ultrasound done on my thyroid because the left side of my neck has been sore for the past 3 months. The Doctor called me to advise the test came back with no lumps etc however there was increased blood flow going to my thyroid and didn't understand why? I am to repeat the ultrasound in 6 months and he is sending me for more thorough blood test for thyroid. Just wondering if anyone else has heard about this increased blood flow with no masses or tumors in the neck? thanks so much
