Hi, I am really looking for some advice. I was diagnosed with Graves in 2014. I was on meds for about a year and have now been off them for a year and I was feeling ok. I recently experienced the same symptoms as before, not sleeping, increased appetite, slight swelling in my lower neck and my heart rate increased as well as other symptoms.My blood tests have come back within the normal range which really surprised me. I am seeing my Gp today to discuss why I am symptomatic - maybe it's a virus or something I'm not sure. Can my test results be normal while still experiencing Graves symptoms.
