I had a total thyroidectomy in 1997 due to a small malignant papillary nodule. Since then I have been on Levothyroxine, initially at 175 mg then 150mg. Around 1 year ago - coinciding with my menopause my TH4 levels have been consistently above the high threshold. The doctor asked me to reduce and now I am on 125 mg but my TH4 is still too high. Over the last 12 months I have been experiencing the following symptoms: pain on top of my esofagus ( it happened 3 times when I had long-haul flights), higher colesterol ( 6.2 when the normal is up to 5.5), passing urine frequently, tiredeness, irritability, blood traces in my urined and over the last 3 months panniculitis on my upper arms. Because of panniculitis ( fat inflammation) I am now investigating Cronic pancreatitis. I read an article associating pancreatitis with hyperparathyroidism and I would like to ask whether hyperparathyroidism can occur in persons who had thyroidectomy and whether there is any association with hyperparathyroidism with hyperthyroidism ( which I have) and and pancreatitis.
