I have currently taken Radioactive Iodine in September and unfourtunately I did go Underactive with my thyroid like they said was a possibility. I have been called back in to the doctors about 2 weeks a go because of my levels being borderline for Hypothyroidism and he told me and is having me wait until I go back to the hospital before risking me on anything. Meanwhile I have been getting worse, my hair gets dull, I get very tired, my hair falls out and I can feel very grumpy and unwell some days. Is this normal before I'm sorted. I feel like Jekyll and Hyde and I hate it when I get moody with people.
