<s>[INST] my father is 73+. He has been having a varying temperature associated with body pain for 20 days. the doctor suspects it to be rat fever and has prescribed medicines. but his esr is 110 which is a worry. his lung x ray shows calciferous deposits. he quit smoking 30 years back. your advice please. [/INST] Thanks for your question I completely understand your question the calcified opacities on the chest X-ray are old healed lesions. You should continue the treatment as told by your physicianpulmonologist can guide you by conducting certain investigations like spirometry and sputum for culture and ll start you on appropriate treatment thanks feel free to ask more questions may god bless your family with good health </s>
