A recent ultrasound identified a nodule (hypoechoic, solid) on my thyroid. I've been experiencing and chasing down many symptoms for the past 2 years. Most prevalent are racing heart (not controlled by current beta blocker meds), tired, dizziness, anxiety. My thyroid labs are always within normal range (TSH, T3 and T4)
Is it possible that the nodule/thyroid is causing the problems, even though labs are normal?
