Hie I am 47 years old. I had thyrodectomy last month during which 4/5 of my thyroid gland was removed. I am now on 50mg of Eltroxin. I will next week be having my first post-operation blood tests. There are days when I feel sick, tightness of my chest particularly the left side. Before the thyroidectomy, my menstruation was very heavy and long. But since the surgery I have not had my period. I am hoping to share and understand thyroid problems. I am not sure if I qualify to be part of this forum because I am based in Zimbabwe. I came across this forum when I was googling about thyroid problems. In Zimbabwe, we don't have the same support networks.
