Hello, Thank you for trusting HealthcareMagic for your health concern Since you are experiencing chills along with chronic cough, Tuberculosis is a possibility especially if you have a recent history of exposure. Sputum analysis, microscopy, culture and chest Xray are required to find firm the diagnosis. Treatment with antibiotics should be initiated once diagnosis is confirmed and measures to prevent spread of infection should also be undertaken. I would also reco.mend checking your thyroid levels, as hypothyroidism can also present with chills(however hypothyroidism is not associated with coughing). Pm Please be advised to follow up with your primary care provider for further evaluation and management Hope this answers your question Please address further questions here Regards Dr.Lekshmi
