Interesting to know so many have this feeling cold thing...yes going to get thyroid tested but really hope its not that. Thanks for all the responses and yes Ark, I get that numbness in the arm even when I don't sleep on it and i get a tingling sort of sensation in my heels too if I lie down so long....the joys eh!!
Thanks again, definitely gonna run this by my doc again.

if your thyroid is a little low (hypo), that's an easy thing for them to adjust. i've been on synthroid (hormone) for several years now, and my numbers have been really good since they started the synthroid. one of the easier things i have to manage.

Could also be Raynaud's syndrome. I have this cold problem - even wear a woolly knitted head-hugger in bed at night, plus the bedsocks and two hotties AND sweat pants - as warmer than jim-jams.

So, check for Raynaud's and also for hypothyroid. In addition get yr blood pressure checked as well as -

many people suffering with autoimmunity have low adrenal gland function. Feeling cold is one symptom. Others include fatigue, feeling lightheaded when going from lying to standing or sitting to standing, very low energy in the morning, trouble sleeping, inflammation, jittery feelings.

I don't generally feel cold. My mother has AS also,her gut component is more severe than mine
Poor absorption renders her fairly anemic and thus always had the feeling of a chill. She added iron rich foods and supplements and removed certain foods that agitated gut and that cold feeling not much of a problem any morr

After reading all your posts, I think I will go and get all my bloods done for iron deficiency, thyroid, adrenal gland and others and rule all these things out....thanks so much for all the sharing, appreciate it much :-)
