Parathyroidectomy...What is that?

On September 27, I had a parathyroidectomy. I have been feeling really tired for a while, and during a routine blood test, it was discovered that my calcium level was really high. I had it checked again in a week, and it was even higher. It was decided that I should go for a scan in Jackson, so I did. The scan showed that I had an adenoma in my lower left parathyroid and that I should have it removed. The surgery was done on Monday and I had to stay in the hospital overnight. Now after about three weeks, I'm beginning to feel like myself again. This picture makes me have chills. I can't imagine this being my neck...
