Can’t seem to regulate body temperature

[MrsCillianMurphy2]

For the last few months I get odd shivers to point where my teeth are chattering.
It strikes with no rhyme or reason - I can be sat practically in the fire or with a big puffa jacket on.
I exercise 3 x a week
Can I do anything to help as it leaves me quite uncomfortable

Have you had your thyroid checked? My Mum was layered up... think 3 tshirts, 2 jumpers, socks etc etc prior to being diagnosed with an Overactive thyroid.

I get the opposite where I pour with sweat whilst others are cold. I have an underactive thyroid.
