Hello. I Am A 66 Year Old Female. I Am

Hello. I am a 66 year old female. I am having a problem with my bodies core. It is a cold feeling in my trunk but is not in the stomach. It has gone from the front of my stomach around to the back and quite often down my leg. This is not painful but very uncomfortable. I have fibermyalgia for which I take remeron more or less for sleep and graves disease and take synthroid. I also have been on a estroderm patch for 16 years and just in the past few weeks stopped the hrt. This feeling has been around for about two years and is only spreading further.
