cold body when sleeping

[bob1483]

I am male, 29 years old, very thin, with mulnutrition from childhood
Since 1 year ago my upper body; upper back, chest and shoulders; gets cold when sleeping, even in a hot room.
It gets so cold that makes me wake up one hour after  sleeping at night.
when i wake up and feel my upper body with my hands it is freezing.
however my hands and feets are warm.
It gets cold when sleeping at daytime but it doesnt wake me up in daytime.
maybe it gets less cold in daytime.
Also i have had a breath shortness and a slight constant pain in my upper back in the same time.
I used to eat one propranolol10mg pill everyday for 4 years for my heart palpitation.
when I quit propranolol 2 months ago it got a little better.
I tested my thyroid and its high.
T4 is near the top of normal range and T3 is higher than normal however TSH is normal.
Can anybody help please and thank you in advance?

Thank you Dr. Lupo
Is it usual to have a low body temperature while having over active thyroid
My oral temperature is about 36.5 while waking up in the morning
however my muscles are even much lower and they are freezing when I touch them in the morning.
And its funny because whenever anybody touch my body during the day while doing usual activity, they say: wowww you are very warm.
does this mean that my body burns all calories during the day and saves nothing for the night?

Would test free T4 and free T3 to verify the borderline T4 and slightly high T3 levels.  With the TSH being normal however, this is not likely a primary thyroid problem.
