I recently had blood test confirm abnormal thyroid function on the hypo side (under active). I felt tired for about 18-24 months but my first major symptom was hives, they lasted 4 months before settling. Around the time it started I noiced that I found it hard to swallow and the skin in my neck felt strange. The hives have now settled though I do get itchy over various areas of my body. The most recent symptom that sent me to the GP was constipation, I think I may have Hashimoto’s and fear I also may have a tumour as I said I did have a sore throat and found it extremely hard to swallow but this was when my hives were at there peak and only lasted a week or two.... sound familiar ?? Off for an ultrasound and thyroid antibody test this week.
