I am 41 yo female. The past 6 mths I have experienced vertigo, tinnitus, numbness in lips, hands, feet, occasional laryngitis, EXTREME fatique, muscle weakness, chest pain and heart palpatations. After months of various dr.s a nodule was inadverently discovered on my thyroid. FNA #1 non-diagnostic, FNA #2 non-diagnostic. In the month between them the size has grown from 2.9 cm to 4.6 cm diameter. All my thyroid blood work shows normal levels (I was never told what the numbers where). Dr. now suggests removal of the left lobe of my thyroid. I guess my question is could this large nodule be causing any of my symptoms even though my levels are normal? I am at a dead end and close to not able to continue working. I have a 2 and 3 yr old and have difficulty at home as well. I don't want to go through a surgery if it does not help me. Please advise. Thank you for your help.
