Brief Answer: Proper review, exclude infection. Detailed Answer: Hi and thanks for the query, Your past medical history for sure compels a careful clinical review. The fact that you are diabetic requires that you ensure that your blood glucose is well controlled, by fr sure doing a good fasting blood glucose and Glycated Hemglobin (HBA1c). Chills in a diabetic compel an exclusion of a probable infection. The inflammatory process in patients with diabetes is not as classic as in non diabetic patients. Chills deserve a infection to be clearly ruled out. A urine culture , blood culture, a complete blood count and C reactive protein measures to carefully rule out an infectious would be very much required. Mild heart problems usually serve as a seat for growth of certain bacteria. In case the mild problem is at the level of the valves, it is common to find a chilly feeling when patients develop an infection therein , generally called infectious endocarditis, that presents as such. A blood culture and cardiac ultrasound, coupled to a proper clinical review is usually sufficient. Consult your primary care physician for a proper review before prescription of drugs. Please, do feel free asking further questions in case you got any specific concerns. Thanks and kind regards. Dr Bain
