My mom has had fever for the last 12 to 13 days along with severe headache. I consulted a physician who prescribed antibiotics and painkillers. We also did several tests including blood and urine, but nothing abnormal was found. However, after taking the medicines, her fever seems to be getting higher. The doctor is still unable to identify the reason for her fever. What could be the possible cause?

If fever persists and all reports are inconclusive, consider testing for viral infections, autoimmune conditions or do imaging. A detailed consult is needed.

I have had joint pain in all joints for the past 2 years. All my blood tests are normal, and the painkillers did not work. No doctor has been able to help me with this. I do not have rheumatoid arthritis, osteoarthritis, high uric acid, or any issues in hemoglobin or urine tests.

I suffered from viral fever one month ago. After 2 to 3 days I got red rashes all over my body. Dengue and Chikungunya tests were negative. Now, since one month I am suffering from acute joint pain. My blood report for ANA is strongly positive. Please suggest?
