I have had a large lump on my thyroid for 5-6 months and ignored it but it is affecting my breathing so I went to get it checked out. I had my blood results back and was told they were outside the ranges but are still normal. I am not sure how it can be outside the ranges and still be normal? Is there such a thing? The nurse who told me the results couldn't give me the range they test by when asked and didn't even have my details up when I started asking questions she was unprepared. I told her I was 6 weeks pregnant and she said that is why my thyroid is swollen until I told her I have had the lump for 5-6 months. I am awaiting my scan date on my thyroid. But am I worrying for nothing or should I be concerned?
