Based on your history you are suffering from type 2 diabetes
, spinal canal
stenosis and constant chills all over body which has to be evaluated.You need to consult family physician/Neurologist
for same.History has to be elaborated, whether chills are associated with fever ,any associated urinary symptoms or you meant to stay terrible neuralgic pain all over body and feeling of chilly sensation( thta can be part of spinal canal stenosis or autonomic neuropathy).You need blood sugar test and control of sugar, urine microscopy and culture to rule out infection, thyroid profile to rule out hypothyroidism
and nerve conduction study
to rule out neuropathy.If everything under normal limits then hypothalamic structural lesion to be ruled out.Hope this will help you.
