Dr. Feld,

 I have thought of you often, and hope that you are well. You may recall that we worked together when I was the General Manager of Disetronic Medical Systems.

I valued your friendship and guidance very highly, and hope to see you in the near future.

 Very best regards,

 Bob Cerza

Why would I have a 4mm calcium deposit in my thyroid.  I had an ultrasound and that was my result.  I can not find anything online about calcium deposits in the thyroid.  My tsh tested almost hyperthyroid then about 6 years ago I was having trouble.  I ate nothing worked out with a personal trainer for the hour that I could get out of bed and I was still gaining weight.  My Dr did another tsh level and I was still in normal range but I was more than half way to hypothyroid.  My dr at that point decided that while in normal range it was not normal for me, so he put me on syntharoid.  I did better never the same as before but good.  A couple years ago I started having trouble again not as severe but tired, weight gain, always COLD (I live in Hawaii and wear sweaters)   I had a tsh level done and the Dr said it was ok I am not sure of the number but he ordered an ultrasound and the calcium deposit is the result.
