I have a lump on the left side of my thyroid and went to doctor several weeks ago, he wanted a blood test and I was referred to a consultant. I had the consultants appointment yesterday and was told that my blood test results were fine and that they didnt show anything abnormal. He said yes definately thyroid and said I would need a scan. The consultant said he would not need to see me again after the scan unless it showed cancer cells. Is this normal? I also feel tired and listless most of the time, have trouble sleeping, cannot lose weight and have constipation. Any advice would be greatly appreciated.
