What causes sudden chills in a 53 year old woman?
Hi I would recommend the following
I did review your concern.
Such changes in temperature sensituvity are seen in thyroid abnormalities.
I would recommend you to do a TSH assay which is a basic thyroid function assay test and its value will let us know thyroid abnormlity if you have any.
I hope this helps.
let me know if you have any more concerns mam.
