I'm sorry to hear that you're experiencing body pain, headache, and weakness. These symptoms can be caused by a variety of conditions, ranging from common viral infections like the flu to other causes such as dehydration, stress, or more serious underlying health issues.

Body pain and headache together with weakness often suggest your body might be fighting an infection or inflammation. Sometimes, muscle strain or injury can also cause these symptoms. Since you mentioned these symptoms without additional details, it’s important to monitor if you develop other signs like fever, difficulty breathing, or severe pain.

For relief, medications like non-steroidal anti-inflammatory drugs (NSAIDs) combined with mild pain relievers can help reduce pain and inflammation. However, it’s essential to use such medications under medical guidance to avoid side effects.

Recommendations:

• Rest and stay hydrated.
• Avoid self-medicating without consulting a doctor.
• If symptoms worsen or persist beyond a few days, or if you experience additional symptoms like high fever, confusion, or difficulty breathing, seek immediate medical attention.
• Please consult a general physician or an internal medicine specialist who can evaluate your symptoms thoroughly and recommend appropriate tests or treatments.
