I was scanned by a friend who is an ultrasound student a few days ago. During the scan, she found multiple thyroid cysts (at least 10+ on each side). Many of the cysts had what looked like little pinheads in them. One of them like looked in it had fluid in it. They were all different sizes. Does it sound like there is a problem with my thyroid? I often feel unmotivated, sometimes jittery, spacey (little concentration and memory). What do you think?
