Hello doctor, I am 52 year old woman. I was diagnosed with hyperthyroidism last year, so I had my thyroid glands remove. I had my medical check to check hormone balance and thyroid balance and everything was normal. From yesterday, a huge bump grew in the top of my throat. It is very painful. If I talk for maybe 1-2 min, it becomes more painful and I start to have nausea. Do you know what may be wrong?
