Well, I had my thyroid results, everything within range and TPO was 176 so I do have hashimotos. The symptoms I have had are due to chronic sinus congestion! Other than the pulsing neck I had absolutely no symptom of blocked sinuses at all. After spending 3 weeks steaming etc I am feeling better but I do now have painful sinuses that throb a lot. I have started taking Iodine again and will build up as before. Thanks again to all who gave advice.
