[/INST] Hello Since you are having fever low grade for last 10 days. Not responding to ordinary treatment. In the last 30 years suffered with Koch's twice. Took treatment, cured. Also taking medicine for high BP. I have seen so many cases (with old tubercular lesion) where cavity get infection and low grade fever developed, so in your case this low grade fever may be due to FRESH TUBERCULAR LESION so get in X-ray chest, sputum for AFB, CBC. So consult a chest tuberculosis specialist and get his opinion. Good luck. </s>
