I'm sorry to hear that you're experiencing backache. While I can't recommend specific medication doses without a proper evaluation, I can suggest some general self-care steps that might help relieve your discomfort:

• Rest and Posture: Avoid heavy lifting and maintain good posture while sitting or standing.
• Heat or Cold Therapy: Applying a warm compress or heating pad can relax muscles, while cold packs can reduce inflammation.
• Gentle Stretching: Light stretching exercises can improve flexibility and reduce muscle tension.
• Over-the-Counter Pain Relief: Medications like paracetamol (acetaminophen) or nonsteroidal anti-inflammatory drugs (NSAIDs) may help, but it's important to use them as directed on the package or by a doctor.

Since back pain can have various causes, including muscle strain, nerve issues, or other underlying conditions, I strongly recommend consulting an orthopedic specialist or a physiotherapist. They can provide a precise diagnosis and tailor treatment, including appropriate medication doses if needed.

If the pain is severe, persistent, or accompanied by other symptoms like numbness, weakness, or bladder/bowel issues, please seek medical attention promptly.To narrow down potential causes, we will need some more information.I understand that you are suffering from backache, but to provide you with the right advice on doses, could you please share your age and gender?
