I'm sorry to hear about your back pain. To help relieve it, you can try the following simple steps at home:

• Rest: Avoid strenuous activities and give your back some time to heal.
• Apply heat or cold: Use a warm compress or heating pad for 15-20 minutes to relax muscles, or an ice pack wrapped in cloth to reduce inflammation.
• Gentle stretching: Light stretches can help ease muscle tightness, but avoid any movements that increase pain.
• Over-the-counter pain relief: Nonsteroidal anti-inflammatory drugs (NSAIDs) like etoricoxib (found in medications such as Etoshine 120) can reduce pain and inflammation. However, these should only be taken after consulting a doctor, especially if you have any existing health conditions.

If your pain is severe, persists beyond a few days, or is accompanied by symptoms like numbness, weakness, or bladder/bowel issues, please seek prompt evaluation by an orthopedic specialist.

For personalized advice and safe medication use, I recommend consulting an orthopedic doctor who can assess your condition and guide appropriate treatment. If the pain worsens suddenly or you experience other concerning symptoms, do not hesitate to seek emergency care.To narrow down potential causes, we will need some more information.Could you please tell me your age and gender?
