I'm sorry to hear that you're experiencing fever and body pain again. Since you took Nimutab (which contains Nimesulide, a painkiller and anti-inflammatory medication) for your symptoms two days ago but now have a recurrence, it’s important to consider a few points:

• Persistence or recurrence of fever and body pain may indicate an underlying infection or condition that needs further evaluation.
• Nimesulide helps reduce pain and inflammation but does not treat infections or the root cause of fever.
• If symptoms return or worsen after initial treatment, it is important to see a doctor promptly for a thorough examination and possibly additional tests.
• Avoid self-medicating further without medical advice, especially since Nimesulide has specific precautions and potential side effects.
• If you experience any new symptoms such as difficulty breathing, chest pain, severe headache, rash, or persistent vomiting, seek emergency care immediately.

Recommendation: Please consult a general physician or an infectious disease specialist as soon as possible to identify the cause of your symptoms and receive appropriate treatment.
