<s>[INST] Hello doctor, I am a 32 year old woman. I weigh 68 kg. I am suffering from fever since one month. Almost daily the temperature is ranging from 99 to 101. Especially in the afternoon. I also have a headache along with fever. Both increases together. Also, there is severe pain in the muscles of the legs below the knee to ankle. The muscles behind the knee (underside of the knee) ache more, and it increases in the evening or night times. I have normal regular home cooked vegetarian food. I have shifted to a new city three months back. Before, I used to exercise, do yoga and walk regularly. But now due to a new place, it is discontinued. I have undergone all tests, and they are normal. Kindly advise. [/INST] Hello. I went through your reports (attachment removed to protect patient identity). Your primary complaint is a fever, especially during the afternoon hours. Start a broad spectrum antibiotic (like Cefuroxime 500 mg twice daily) after a blood culture and come back with investigations. Regards.
