First two weeks on mystery medicine

It has been about 2 weeks since I started the first thyroid medicine.  I am pretty sure it is the natural thyroid medicine Armour or something similar.  I noticed the second day on the medicine that my hands were warm.  Really really warm!  Warm hands and feet is a new experience for me.  Never in my life have I had my hands and feet the same temperature as the rest of me.  The veins in my hands/arms etc. are really sticking out from the increased blood flow.  I think I had a virus so I don't know what of my other symptoms were from that or from the new medicine.  The warm hands are definitely from the medicine and it is new.
