What potential medical conditions could cause a combination of persistent headache, low-grade fever (99?F), body aches, weakness, diarrhea, and acidity, particularly when daily paracetamol use has not resolved the symptoms?
A combination of a low-grade fever, body aches, weakness, diarrhea, and acidity often points to a common viral infection, such as viral gastroenteritis (stomach flu). Sometimes, daily use of paracetamol can actually irritate your stomach, contributing to the acidity, or even lead to medication-overuse headaches if used continuously. Please focus on staying well-hydrated with water and oral rehydration solutions. Since your symptoms are persisting despite paracetamol, I highly recommend consulting a doctor. They can help identify the exact cause and guide you on the safest way to recover.
