I had an overactive thyroid about 4 years ago so I'm aware of how it makes you feel. I notice about 4 weeks ago the bottom of my neck was swelling and I got symptoms like fidgety, thirsty, heart palpertations, lack of energy, feel week, tired but trouble sleeping. I've had blood test and my tsh has come back at 1.2. Doctors want to do an ultrasound on my neck. Just feel like I'm not getting anywhere and I'm getting fed up of not having the energy for anything. Is it possible to have a "normal" reading but have all the symptoms ? Need help on what to do pleaseeeeeeeeeeee.
