Pain between the chest and upper back that worsens with arm movement or bending forward may be related to muscle strain or inflammation. A combination medicine like Neorelax MR Tablet, which contains a muscle relaxant, an anti-inflammatory, and a pain reliever, might help reduce muscle stiffness and pain.

• You should consult a specialist doctor, such as an orthopedist or a pain management specialist, to confirm the cause and get a proper prescription.
• Avoid heavy lifting or movements that worsen the pain until evaluated.
• Applying heat or cold packs may provide temporary relief.
• If prescribed, take medications like Neorelax MR Tablet exactly as directed and report any side effects such as nausea or dizziness.
• Seek immediate medical attention if you experience chest pain radiating to the arm, shortness of breath, or severe weakness.
